bug#57023: [PATCH] Take last libgccjit.dylib or .so from homebrew

This patch fixes a bug where building with native-compilation with the
latest libgccjit from homebrew fails, because an extra copy of the dylib showing up
in the output of brew ls results in a malformed CFLAG.

Subject: [PATCH] Take last libgccjit.dylib or .so from homebrew

Homebrew now shows multiple dylibs, under "<version-number>/" and
"current/". One is a symlink to the other, so it doesn't matter which
we choose, but otherwise the linker flag gets malformed (ends up as
"-L/whatever/12/libgccjit.dylib\n/whatever/current/")
