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.
This allows us to add keys that don't exist in the CMake template.
I added the keys from the Info.plist that was generated by our SCons build
to the new template.
