The update to stage0-posix, mes-boot and tcc-boot0 are now in
core-updates, and I didn't see any regressions on x86_64/i686.

Currently there's an issue on riscv64/ppc64le (and maybe others?) about
zstd not being available for patch-and-repack for make-boot0 and
perl-boot0 (and probably others).

you might need ,@(if (target-hurd?)

my debugging trick is to make the changes and then check the "else" case
to see if it's changed anything there.  Since it looks like you're not
trying to change the flags for other architectures the derivation
shouldn't change if you've gotten the rest of the patch correct :)
