linux-user: ppc: mark as long long aligned
The SysV PPC32 ABI dictates that long long (64bit) parameters are pass in odd/even
register pairs. Because unlike ARM and MIPS we start at an odd register number,
we can reuse the same aligning code that ARM and MIPS use.
Clarified inline comment that it is SysV ABI that requires long long aligned
parameters - Riku
