Solomon Peachy caaea275eb libspc: Temporarily disable problematic armv4 asm optimization
asm volatile (
    "mov    %[t0], %[out], asr #11  \n"
    "mul    %[out], %[t0], %[envx]  \n"
    : [out]"+r"(output), [t0]"=&r"(t0)
    : [envx]"r"((int) voice->envx));

This is resulting in "Rd and Rm should be different in mul" error,
because the compiler is putting [out] and [t0] into the same
register.

After some poking there doesn't appear to be a sane way to change
the constraints, so just disable it for now.
