I guess you mean moving #ifdef SBC_BUILD_WITH_SSE_SUPPORT into
sbc_primitives_sse.c, same for mmx, right? I will fix that, although I
was thinking on not even compiling those files when the config option
is not enabled which would result in undefined symbols, I can however
have alternative versions when its options are not enabled which
basically does nothing.
