sparc64 needs to use CFLAGS with CC to link properly using gcc the
attached patch fixes this issue

Patch submitted originally by Dennis Gilmore.

For multilib support, sparc needs libselinux (and libsepol) to be built
as sparc
(32bit) and sparc64 (64bit). sparc builds fine (-m32 is assumed by the
compiler), but when building for sparc64, we need all compile and link
operations to have -m64 passed for it, or else gcc will mismatch (it
will make
sparc64 object files, then try to link them as a 32bit library) and the
build fails.

The easiest way to ensure safe and consistent builds is to universally apply
CFLAGS whenever calling CC, which is what this patch does.
