Thanks, that worked! I read most of the Guix manual, but I had forgotten
about the `--with-c-toolchain` option. Searching for it in the manual
also made me find the `package-with-c-toolchain` function, which does
the same thing from Scheme code.
Though there’s something weird about Mesa’s build process. Different
libraries end up linked to different GCC versions. :-/
$ guix build --system=i686-linux --with-c-toolchain=mesa=gcc-toolchain@10 mesa

Also the 32-bit game I’m trying to run somehow gets linked to different
Mesa builds too:
libGL.so.1 =>
/gnu/store/27yzdsj09mm3ijj4zhikcgjjqjlr74yc-mesa-20.2.4/lib/libGL.so.1

/gnu/store/27yzdsj09mm3ijj4zhikcgjjqjlr74yc-mesa-20.2.4/lib/libglapi.so.0
(0xf6621000)
The 27yz… build is the GCC 10.3.0 one, and 6k4wj… is the GCC 7.5.0 one.
Perhaps my time would be better spent trying to help get ‘core-updates’
in shape rather than trying to work around a 4 years old compiler bug¹.

¹ https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=866354 – the bug is
in armel, but I’m getting the exact same error message in Mesa, so I
suspect it also affects i686.
