So, when I say "fixed" here, all I managed to do is stop a gexp ending
up in the builder script of gcc-boot0. I managed to fix some of the
problems with the changes I made, but then I tried cross building from
x86_64-linux, up popped a package which failed to build because it was
missing the patch. This is relevant as it blocks machines using
childhurds from reconfiguring past the latest core-updates merge.

While it caused problems, using gexps at least avoided the problem where
you need to have the patch in the native-inputs as well, so to continue
going round in circles, that's maybe the direction to now go. As the
next step though before using gexps in gcc-11, any packages inheriting
from gcc-11 need to be changed to use gexps for the phases.

I've attempted to do that in #63329 [1], I'll wait to see what the data
service makes of the changes to see how successful I've been at avoiding
rebuilds.
