Not really, its actually intentionally designed like this since its
pointless rebuilding gcc-cross multiple time just because we want to use
it with a different sysroot. We therefore just pass in the arguments to
the compiler to ensure it uses the right one. If you remove them, you
hit the problems you describe.

We should probably compile in a bogus sysroot so it never works and
makes this kind of issue more visible.
