Description
This patch will automatically detect the host CPU for MacOS X systems. It works for both PowerPC and Intel. It also removes the memalignhack for MacOS X builds since allocation on MacOS X always returns an aligned address.

I have applied this, mostly as given. I suspect there will be some negotiation of what P6 actually means, and what ARCHFLAGS should actually be for an Intel Core chip, though.
e.g. -march=pentium-m -sse -sse2 -sse3 -mmx

The PPC part of this is working fine. It gives me CPU-optimised builds by default, which isn't what packagers want, but they should be smart enough to remove the optimisation if needed.
I haven't seen any discussion of X86 flags on the Wiki, so I will assume that everyone is happy for now.
