Applied compile and link flags from SCons build for OS X to CMake build.

Browse Source 
The following changes were made:
Restricted the "-march=core2" option to i386 because the first Intel Macs
had Intel Core CPUs, not Core2.
Removed the "-mdynamic-no-pic" flag as GCC lists it as a PPC specific flag.
Removed "-Wl,-read_only_relocs,suppress" because it seems to be related
to "-mdynamic-no-pic" and I see no need for it.
Removed "-Wextra-tokens -Wnewline-eof" because they are GCC specific and
not OS X specific.
