    Do not pass -mmmx or -msse2 to the compiler · 9c61b594

    x86 GCC does not need those parameters to compile MMX or SSE assembly
    or built-in intrinsics (contrary to ARM GCC w.r.t. NEON). They only
    allow the compiler to issue MMX or SSE instructions for the plain C
    code. We already rely on this tolerant compiler semantic for the CPU
    detection code, and for some optionally accelerated filters (e.g.
    Disabling MMX and SSE for non-assembly code should have no or
    negligible effects on the affected plugins. On the other hand, it
    ensures that the plugin descriptor can be run by non-MMX/non-SSE CPUs.
