05aca09381build: Patch Qt to handle minimum macOS version properly (Hennadii Stepanov) Pull request description: This PR is: - required to [switch](https://github.com/bitcoin/bitcoin/pull/28622) to macOS 14 SDK (Xcode 15). - an alternative to https://github.com/bitcoin/bitcoin/pull/28732 and https://github.com/bitcoin/bitcoin/pull/28775. Qt relies on the `__MAC_OS_X_VERSION_MIN_REQUIRED` macro, which is set in the `AvailabilityInternal.h` SDK header to the value provided by the Clang driver from the `-mmacos-version-min` / `-mmacosx-version-min` option. Xcode 12 SDK expects the OS-specific `__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__` macro: ```c++ #ifndef __MAC_OS_X_VERSION_MIN_REQUIRED #ifdef __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ /* compiler for Mac OS X sets __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ */ #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ #endif #endif /* __MAC_OS_X_VERSION_MIN_REQUIRED*/ ``` In the other hand, Xcode 15 SDK expects a general `__ENVIRONMENT_OS_VERSION_MIN_REQUIRED__` macro: ```c++ #ifndef __MAC_OS_X_VERSION_MIN_REQUIRED #if defined(__has_builtin) && __has_builtin(__is_target_os) #if __is_target_os(macos) #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_OS_VERSION_MIN_REQUIRED__ #define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0 #endif #elif __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ #define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0 #endif /* __has_builtin(__is_target_os) && __is_target_os(macos) */ #endif /* __MAC_OS_X_VERSION_MIN_REQUIRED */ ``` The latter macro is not provided by LLVM Clang untilc8e2dd8c6f, which is available in Clang 17. The suggested patch makes Qt "borrow" the `__MAC_OS_X_VERSION_MIN_REQUIRED` value from `MAC_OS_X_VERSION_MIN_REQUIRED`, which is set in the `AvailabilityMacros.h` SDK header.
