Btw, even with the fixes from this PR/79281 and PR/79037, the "go" command is
still crashing on m68k with gcc-6. It might be possible that this is the reason
the build of gcc-7 fails for this reason, doesn't it?

The crash in "go" on gcc-6 seems to be related to Go's Mutex type as this code
[1] crashes as well. I will file a separate bug report for that.
