core-updates: Build failure for file on i686-linux

Hi,

Trying to build 'wine-minimal for x86-64 on core-updates, the following error is hit while building 'file for i686-linux:

/tmp/guix-build-file-5.42.drv-0/file-5.42/src/.libs/file: symbol lookup error: /gnu/store/wb8f0ydwl7458ixgsmx65x5ni54c7zgk-glibc-mesboot-2.16.0/lib/libpthread.so.0: undefined symbol: h_errno, version GLIBC_PRIVATE

make[2]: *** [Makefile:857: magic.mgc] Error 127

make[2]: Leaving directory '/tmp/guix-build-file-5.42.drv-0/file-5.42/magic'

make[1]: *** [Makefile:462: all-recursive] Error 1

make[1]: Leaving directory '/tmp/guix-build-file-5.42.drv-0/file-5.42'

make: *** [Makefile:371: all] Error 2

The build failure can be easily reproduced with `./pre-inst-env guix build --system=i686-linux file`, and I have bisected the failure on core-updates to commit 25b30622b4a77cd4b2965b9d62fa310a22413d54 "gnu: glibc: Update to 2.35.".

I suspect this may be causing many i686 failures on core-updates since `./pre-inst-env guix refresh -l file` reports 7732 packages that would have to be built to ensure 16065 dependent packages are rebuilt.

Cheers,

Kaelyn

As a bit of followup, this bug still exists with the latest core-updates commit. This not only affects i686 systems, but also some x86_64 packages like wine/wine64 which require a 32-bit build in addition to a 64-bit one.
