bug#50031: gcc-core-mesboot1 may not be deterministic

[Thiago Jung Bauermann via Bug reports for GNU Guix <bug-guix@gnu.org>]

Hello,

Using Guix from both the ‘master’ branch¹ and from the ‘core-updates-frozen’
branch², the following command fails:

--8<---------------cut here---------------start------------->8---
$ guix build --check \
    -e '(@@ (gnu packages commencement) gcc-core-mesboot1)’
    ⋮
guix build: erro: derivation `/gnu/store/qbnxfv7v7288iisl44kccz68k0pv9qdi-gcc-core-mesboot1-4.6.4.drv' may not be deterministic: output `/gnu/store/rn3qvn67nraicabvlrx1rhw6nsjrpgpx-gcc-core-mesboot1-4.6.4' differs
--8<---------------cut here---------------end--------------->8---

During the stripping phase, there are many of these warnings, which may be
related:
