Fixed bugreport:5990 OSX compiling error / warnings

Bug in Detail:
 - Misplaced LDFLAGS uage in some Makefile templates (by passing them to the compiler not to the linker.)
 - Wrong usage of volatile (a functions return value couldnt be declared to return volatile :D )
 - Unsupported Inline ASM using lock xchg operation on llvm-gcc .. (apple loves this ..)

Fixed by:
 - Removed unnecessary LDFLAGS 
 - Removed unnecessary volatile declarator
 - Replaced InterlockedExchange and InterlockedExchange64 with gcc intrinsics.
