[oe] klibc problems

[Graeme Gregory]

Ok, its no mystery to some people that klibc has problems with modern
kernels.

But I think we also have a problem with the package in OE. Seeing as
klibc is machine dependent in that it includes mach-XXX/include/mach/*.h
files it really should not be staged as part of the base arch. I think
we need to stage it into ${MACHINE_ARCH} the same was as the kernel is.

We can then work on fixing the application compiles. I think I have a
suitable hack.
