Hi Daniel.

It looks like we visit arch/x86/kernel/acpi/realmode/Makefile
twice in parallel as we have both make[4] and make[3] in play here.
Or maybe we have a dependency bug in the Makefile.

Can you try to do a:
make V=1 and post the output a few screen fulls before and until
the bug triggers.
They I will see if I can work out what is happening.

Thanks,
	Sam
