I've merged #63329 now, and also reverted to the gexp based patching in
gcc-11.

The childhurd system test builds for me at least, although it seems to
fail when run.

Native building for i586-gnu seems to have multiple problems, although I
think the gcc-cross-boot0 source issue is the one that seems hardest to
work around to me.
