    x86_64: Exclude SSE, AVX and FMA4 variants in libm multiarch
    
    When glibc is built with ISA level 3 or higher by default, the resulting
    glibc binaries won't run on SSE or FMA4 processors.  Exclude SSE, AVX and
    FMA4 variants in libm multiarch when ISA level 3 or higher is enabled by
    default.
    
    When glibc is built with ISA level 2 enabled by default, only keep SSE4.1
    variant.
    
    Fixes BZ 31335.
    
    NB: elf/tst-valgrind-smoke test fails with ISA level 4, because valgrind
    doesn't support AVX512 instructions:
