Yes, I only had gcc in my environment (via
“guix environment --ad-hoc”).  gcc-toolchain does not seem
to include the needed 32-bit gnu/stubs-32.h either when
built for x86_64.  I also have to set the glibc or
gcc-toolchain include path from the store anyway otherwise
“guild compile-ffi” cannot find stdlib.h.

$ guix environment --ad-hoc gcc-toolchain
$ cd build/nyacc/src/nyacc/examples
$ source env.sh
$ cd ~/keep/projects/pelzfloriande-website
$ guild compile-ffi gettext-po.ffi

On Parabola I probably needed the lib32-glibc package.
