+    build: use -fcommon to retain legacy behaviour with GCC 10

+    GCC 10 started using -fno-common by default, which causes issues with

+    the issue, 18363b4f010da9ba459b13310b113ac0647c2fcc but is non-trvial
+    to backport, and was broken in at least one way, see the followup in
+    commit 7650321ce037302bfc2f026aa19e0213b8d02fe6.
+    
+    For now, retain the legacy GCC behaviour by passing -fcommon when
+    building glibc.

+    rt: Turn forwards from librt to libc into compat symbols [BZ #24194]
+    
+    As the  result of commit 6e6249d0b461b952d0f544792372663feb6d792a
+    ("BZ#14743: Move clock_* symbols from librt to libc."), in glibc 2.17,
+    clock_gettime, clock_getres, clock_settime, clock_getcpuclockid,
+    clock_nanosleep were added to libc, and the file rt/clock-compat.c
+    was added with forwarders to the actual implementations in libc.
+    These forwarders were wrapped in
+
+    #if SHLIB_COMPAT (librt, GLIBC_2_2, GLIBC_2_17)
+    
+    so that they are not present for newer architectures (such as
+    powerpc64le) with a 2.17 or later ABI baseline.  But the forwarders
+    were not marked as compatibility symbols.  As a result, on older
+    architectures, historic configure checks such as
+    
+    AC_CHECK_LIB(rt, clock_gettime)
+    
+    still cause linking against librt, even though this is completely
+    unnecessary.  It also creates a needless porting hazard because
+    architectures behave differently when it comes to symbol availability.

+    [RS6000] Don't pass -many to the assembler
+
+glibc builds are failing when an assembly implementation does not
+declare the correct '.machine' directive, or when no such directive is
+declared at all.  For example, when a POWER6 instruction is used, but
+'.machine power6' is not declared, the assembler will fail with an error
+similar to the following:
+
+    ../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages:
+     24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb'
+
+This patch adds '.machine powerN' directives where none existed, as well
+as it updates '.machine power7' directives on POWER8 files, because the
+minimum binutils version required to build glibc (binutils 2.25) now
+provides this machine version.  It also adds '-many' to the assembler
+command used to build tst-set_ppr.c.
+
+Tested for powerpc, powerpc64, and powerpc64le, as well as with
+build-many-glibcs.py for powerpc targets.

+    riscv: add asm/unistd.h UAPI header
+
+    Marcin Juszkiewicz reported issues while generating syscall table for riscv
+    using 4.20-rc1. The patch refactors our unistd.h files to match some other
+    architectures.
+
+    - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
+    - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
+    - Adjust kernel asm/unistd.h
+
+    So now asm/unistd.h UAPI header should show all syscalls for riscv.
+
+<asm/syscalls.h> may be restored by
+
+Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header
+Date: Tue, 11 Dec 2018 09:09:35 +0100
+
+UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header,
+which did resolve issue with missing syscalls macros resulting in
+glibc (2.28) build failure. It also broke glibc in a different way:
+asm/syscalls.h is being used by glibc. I noticed this while doing
+Fedora 30/Rawhide mass rebuild.
+
+The patch returns asm/syscalls.h header and incl. it into asm/unistd.h.
+I plan to send a patch to glibc to use asm/unistd.h instead of
+asm/syscalls.h
+
+In the meantime, we use __has_include__, which was added to GCC 5, to
+check if <asm/syscalls.h> exists before including it.  Tested with
+build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7.
+
+	[BZ #24022]
+	* sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if
+	<asm/syscalls.h> exists with __has_include__ before including it.

 ## Deterministic macOS App Notes
 
-macOS Applications are created on Linux using a recent LLVM.
+macOS Applications are created in Linux by combining a recent `clang` and the Apple
+`binutils` (`ld`, `ar`, etc).
 
-All builds must target an Apple SDK. These SDKs are free to download, but not redistributable.
-See the SDK Extraction notes above for how to obtain it.
+Apple uses `clang` extensively for development and has upstreamed the necessary
+functionality so that a vanilla clang can take advantage. It supports the use of `-F`,
+`-target`, `-mmacosx-version-min`, and `-isysroot`, which are all necessary when
+building for macOS.
 
-The Guix build process has been designed to avoid including the SDK's files in Guix's outputs.
-All interim tarballs are fully deterministic and may be freely redistributed.
+Apple's version of `binutils` (called `cctools`) contains lots of functionality missing in the
+FSF's `binutils`. In addition to extra linker options for frameworks and sysroots, several
+other tools are needed as well such as `install_name_tool`, `lipo`, and `nmedit`. These
+do not build under Linux, so they have been patched to do so. The work here was used as
+a starting point: [mingwandroid/toolchain4](https://github.com/mingwandroid/toolchain4).
 
-Using an Apple-blessed key to sign binaries is a requirement to produce (distributable) macOS
-binaries. Because this private key cannot be shared, we'll have to be a bit creative in order
-for the build process to remain somewhat deterministic. Here's how it works:
+In order to build a working toolchain, the following source packages are needed from
+Apple: `cctools`, `dyld`, and `ld64`.
+
+These tools inject timestamps by default, which produce non-deterministic binaries. The
+`ZERO_AR_DATE` environment variable is used to disable that.
+
+This version of `cctools` has been patched to use the current version of `clang`'s headers
+and its `libLTO.so` rather than those from `llvmgcc`, as it was originally done in `toolchain4`.
+
+To complicate things further, all builds must target an Apple SDK. These SDKs are free to
+download, but not redistributable. See the SDK Extraction notes above for how to obtain it.
+
+The Guix process builds 2 sets of files: Linux tools, then Apple binaries which are
+created using these tools. The build process has been designed to avoid including the
+SDK's files in Guix's outputs. All interim tarballs are fully deterministic and may be freely
+redistributed.
+
+As of OS X 10.9 Mavericks, using an Apple-blessed key to sign binaries is a requirement in
+order to satisfy the new Gatekeeper requirements. Because this private key cannot be
+shared, we'll have to be a bit creative in order for the build process to remain somewhat
+deterministic. Here's how it works:
 
 - Builders use Guix to create an unsigned release. This outputs an unsigned ZIP which
-  users may choose to bless, self-codesign, and run. It also outputs an unsigned app structure
-  in the form of a tarball.
+  users may choose to bless and run. It also outputs an unsigned app structure in the form
+  of a tarball.
 - The Apple keyholder uses this unsigned app to create a detached signature, using the
-  included script. Detached signatures are available from this [repository](https://github.com/bitcoin-core/bitcoin-detached-sigs).
