Subject: [PATCH] GitHub: allow not caching the Golang build cache

This is a tradeoff of disk space (and with that cache size) and
compilation speed. Because we're still running into disk full errors
with the full build cache, we remove it for the cross compile step.
Which means we'll do more work each time.
