Subject: [PATCH] keg_relocate (linux): prepend `gcc/lib/current` to `RPATH`
 when needed

This should help keep bottles that require GCC working when
Homebrew/homebrew-core#106755 is merged.

This only works on freshly-poured bottles. Previously installed bottles
will still break on systems with a host GCC older than GCC 11.
