The -B flag to gcc (and libgccjit) allows us to specify where it can
find things it needs to correctly compile code (both programs and
libraries) without adjusting any environmental flags: So, no need to
wrap the program for a PATH entry containing binutils, and no need to
explicitly pass a linker path anymore.

This way, we don't have to drag clang or binutils/binutils-wrapped
into the emacs closure, and can instead rely on using the correct one
for the platform we're running on.

Since Darwin's linker does not understand LIBRARY_PATH, we have to set
the library path as explicit linker flags: This requires a very recent
feature/native-comp emacs revision, but it runs on Darwin and
correctly compiles files at runtime.
The latter doesn't exist on Darwin (and, presumably, other targets as
well). This change allows emacsGcc from emacs-overlay to attempt to
build where previously, the derivation would error out.
