[PATCH]Add include guard to sparc.h when using assembly

[Gedare Bloom]

I don't think the problem is sparc.h, which already does include
within it some asm guards. Perhaps we should dig into the include to
figure out where the breakage occurs. A simple test case would be
helpful. I suspect the compiler winds up in basedefs.h and there are
missing guards there. basedefs.h does not look quite "asm" safe.
