Thanks!  We really could use help with this (Danny?).  To paint the
picture for people listening in: Next to ARM it may need some Guix
skills, or even more work to reproduce our experimental ARM bootstrap
outside of Guix.

I'm a bit hesitant about the timing, because I cannot make much time the
coming week.

A very short summary of where we are, on wip-arm-bootstrap, building
gawk-mesboot0

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix build -e '(@@ (gnu packages commencement) gawk-mesboot0)'
--8<---------------cut here---------------end--------------->8---

produces a gawk binary that fails to increment a variable

--8<---------------cut here---------------start------------->8---

So could be anything, could bin in tcc-boot or in gawk-mesboot0...

Thanks for reaching out!
Greetings,
Janneke
