Indeed!  I noticed this same issue the other day.  Check out commit
2ee2e2721367cc242ceb0e4b364468870a87f0b4:

    https://git.savannah.nongnu.org/cgit/gash/gash-utils.git/commit/?id=2ee2e2721367cc242ceb0e4b364468870a87f0b4

I recommend that you take a look at the “wip-gcc-mesboot” branch.  It
has a couple “from the hip” changes that I made while looking at getting
Gash-Utils to handle more of the work in “commencement.scm”.  Last week
I was able to build to “gcc-mesboot1” with only Make, Diffutils, patch,
and Gzip (the first three were there before the “Scheme-only” bootstrap,
and Gzip saves writing “(delete 'compress-documentation)” over and
over).  Unfortunately, building Glibc after that is quite difficult.  To
do it with Gash-Utils, we would need (at least) to support redirects in
AWK and the “-t” and “-k” flags in sort.  For fun, I tried building Gawk
and Coreutils at this point (using the ancient versions that we
bootstrap with now).  That let me build Glibc, but then I hit a problem
with the “po2test.sed” script while building “gcc-mesboot”.  I tried
again with ancient GNU Sed, but the build seemed to hang during a
configure test.  I suspect adding Bash to the mix might fix it, but I
haven’t tried yet....

Back to the matter at hand: I’m closing this bug since it’s already been
fixed.  :)

Gash-Utils ‘uname’ seems to be confused:

--8<---------------cut here---------------start------------->8---
$ $(guix build -e '(@@ (gnu packages commencement) gash-utils-boot)')/bin/uname -a
Linux ribbon 5.10.10-gnu #1 SMP 1 x86_64 GNU/Linux
$ $(guix build -e '(@@ (gnu packages commencement) gash-utils-boot)')/bin/uname -s
