But i can :)
~guix environment --ad-hoc -e '(list (@@ (gnu packages gcc) gcc-9) "lib")'~

Why not keep both?

Anyway, ~guix environment --ad-hoc gcc-toolchain:lib~ resulting in these:
--8<---------------cut here---------------start------------->8---
guix environment: error: package `gcc-toolchain@9.1.0' lacks output `lib'
--8<---------------cut here---------------end--------------->8---

in: ~guix environment --ad-hoc gcc-toolchain~
libstdc++, as well some other gcc libs not presented too.
