x86/kbuild: Eliminate duplicate command line options
The options -mno-mmx and -mno-sse are unconditionally added to KBUILD_CFLAGS in both branches of an ifeq and through a $(cc-option) further down. We can safely remove the first instances. In fact, since the -mno-mmx and -mno-sse options were introduced simultaneous with the other two options in the $(cc-option) [according to http://www.gnu.org/software/gcc/gcc-3.1/changes.html], and since the former were unconditionally used, one can deduce that only gcc versions knowing about all four are supported. So also eliminate the $(cc-option) wrap.
