Grepping "!<arch>" in gcc-toolchain:static gives me libanl.a, libdl.a,
libpthread.a, librt.a and libutil.a.  Currently only librt.a is not
present in gcc-toolchain:out, so the proposal is really reasonable for
me.

Cc-ing Josselin since they have sent a patch to #63258.

Hi Josselin, what's the current state of the patch?  Can you resend it
to guix-patches to trigger the build process?


Thanks
