sparc64-linux-gcc: error: unrecognized command-line option '-mxsave'

Is there something else funky going on here?  All of the "-mxsave" flags
that I can find are under checks for x86 builds, like:

	ifeq ($(CAN_BUILD_I386),1)
	$(BINARIES_32): CFLAGS += -m32 -mxsave
	..

I'm confused how we could have a sparc64 compiler (and only a sparc64
compiler) that would end up with "-mxsave" in CFLAGS.

Hi Dave,

We can reproduce the error and have no idea too, but we have disabled
the test for selftests on non-x86 arch.
