hm, I tried to fix this but my sparc32 cross-compiler broke.

ARCH=sparc:

scripts/mod/empty.c:1: error: -m64 is not supported by this configuration
scripts/mod/empty.c:1: error: -mlong-double-64 not allowed with -m64

How'd that -m64 get in there?

I haven't tested sparc32 in some time so perhaps I've forgotten the magic sauce.
