Updated version of Rask Ingemann Lambertsen's patch

I'm bumping this bug to make people aware that it still exists and that people
are affected by it.
On OpenRISC (not in main tree arch), the ABI states that var args are always
passed on the stack, thus making it impossible to build a working native
compiler
when this bug is present.

Attached is an updated version of the patch posted by Rask Ingemann Lambertsen,
bringing it up to date with the current svn.
