[RESEND] Mac OS X Winebuild and asm

Hi!

Here is (again) the patch for Mac OS X and PowerPC assembler syntax. 
This time it has been a lot more tested, and it is ok. It add support 
for Mac OS X PowerPC Syntax. I resend it because I didn't see any reply 
on this one, and I am soon going on holidays, so... ;)

Thanks again,

Pierre

ChangeLog:
- Change __PPC__ to __powerpc__
- Add a special init section for Mach-O
- Change the weak attribute to weak_import on darwin
- Support for multiple PowerPC assembler syntax
