librt has been integrated into libc since glibc 2.34.

gcc-toolchain:static should provide an empty library to satisfy the
linker:
--8<---------------cut here---------------start------------->8---
$ guix shell gcc-toolchain:static -- sh -c 'ls $GUIX_ENVIRONMENT/lib/librt*'
/gnu/store/8fv6xh7nyyb4hsi7b7p2s2ihpsj0lvs9-profile/lib/librt.a
--8<---------------cut here---------------end--------------->8---

Thanks
