I think so. I can't see any way to get this path information out of
the brew command. Perhaps we need to do some find magic to get the
actual directory...?

This appears to work, but I don't see anything else like it in
configure.ac, so it's maybe not a good idea:

        brew_libdir=`dirname ${BREW_LIBGCCJIT_PREFIX}/lib/gcc/*/libgccjit.so`
        LDFLAGS="$LDFLAGS -L${brew_libdir} -I${BREW_LIBGCCJIT_PREFIX}/include"

The alternative is just to leave people to set up these flags
themselves, but I'd rather not if we can avoid it.
