The GPU/VPU libraries should be looking at the kernel headers, not the
libc headers.

If you put the kernel headers in as libc headers, it means the whole
stack is machine specific and will entirely rebuild with each machine
switch. The libc headers are meant to be machine independent.

I suspect the situation after these patches still isn't perfect (see my
other reply) however it is *much* improved and I much appreciate this
being fixed. We've seen build repeated failures on the autobuilder for
what seems like months due to this problem.

Cheers,

Richard
