Huh?
I cross build all the time, and the machine/ includes are always
right, with or without this patch. Maybe you could explain what you
mean here...
The issue is that old code has
#include <i386/isa.h>
or whatever in it, and we need to have an i386/isa.h that's just
#include <x86/isa.h>

I'm guessing what was meant is that one benefit of a merged tree (like
we will have with powerpc) is that you can do cc -m32 on a 64-bit host
to get a 32-bit binary, which is less than trivial now.
