libgcc: remove unused package

trofi · trofi · commit 9818d120be61 · 2023-05-13T17:22:17.000+01:00
`libgcc` is not usable as is and as a result no packages use it today.
`gcc.cc.libgcc` should provide the same library. But ideally it should
not be used at all as it's an implementation detail of `gcc` support
libraries.
