Ok with how you have SYSROOT + ROOT + PORTAGE_CONFIG working I think
I've been able to come up with a decent set of cross compile wrappers
that should be usable by everybody for the ideal cross compile setups.
No more of the 'xmerge' foo. This should do it right.
I want you to review.. And then tell me if it should be apart of
crossdev or another pkg.
