Mac and cheese... err... Linux

Big thanks to Mike Blackburn for some fixes for the Macintosh support and for implementing the Linux PPC support! Well done, Mike.

After this (and this) update Mac OSX 10.4 is supported too: the instruction cache flush needed a different implementation.

Also Linux PPC users can benefit from the PowerPC JIT.

The more the merrier.

I try to keep this post short. New update is available:

• MacOSX Darwin PowerPC support is implemented.
• Fixed address distance calculation for the PowerPC native relative branch instructions.
• Refactored the boolean values to use TRUE/FALSE preprocessor defines.

Big thanks goes to Tobias Netzel, who implemented the MacOSX support for the JIT compiling and helped me chasing down one more sneaky bug.

Some details on the bug: previously the negative relative branch calculation was completely wrong, which caused jumping to invalid addresses among certain situations and made the application crash.
