according to PP50 of
http://developer.apple.com/Mac/library/documentation/DeveloperTools/Conceptual/LowLevelABI/100-32-bit_PowerPC_Function_Calling_Conventions/32bitPowerPC.html#//apple_ref/doc/uid/TP40002438-SW20
it's doing the Right Thing. Structs <=8 bytes should be returned in EAX:EDX.
Conversely, the PPC ABI calls for structs to be returned into an area pointed
to by GPR3.
So, it seems that what we need to do is to make the struct > 8 bytes and then
the same test should apply to PPC and i686.
We should not be running this for m64 code (I had already included the /* {
dg-require-effective-target ilp32 } */ as part of the remaining patches for
PR35165 ... )
