Some more GCC 4 and PPC fixes.

* Mesa doesn't compile yet, as some PPC specific stuff seems to be
  missing, Philippe?
* Cortex and some other stuff has been marked x86-only, although
  it's more of a "GCC 2.95.3"-only.
* I'm not sure if it's a bug in GCC 4, or if that's what the C
  standard demands, but sizeof(some_type::some_field) is not
  valid anymore :-/
