PPC patch for objc2-sharp

The unit tests crash with an abort trap when an IntPtr return value is used and
fail with unexpected values when bools are used. I've attached a patch for both
of these which works on PPC and will probably work on Intel.

For bool, I think we were wrong even on Intel. The code was marshaling bools as
4-byte values which is not correct for objective-C which uses BOOL, a 1-byte
type, instead of the C++ bool or C-99 _Bool.

The IntPtr problem seems to be some sort of ABI difference that I don't
understand fully. I fixed it by telling Cocoa that IntPtr's are ints instead of
object pointers.
