    Fix fma test case [PR97018]

    These tests are written for 256 bit vector. For -march=cascadelake,
    vector size changed to 512 bit. It doubles the number of fma
    instruction and test fail. Fix is to explicitly disable 512 bit
    vector by passing additional option -mno-avx512f.

    Tested on x86-64.
