plink2 is one of the packages implementing simde. It looks like for certain architecture flags, the source code also expects to be able to make use of fma instructions, which are CPU specific. Not all x86_64 processors support fma, so -mfma would be another build option to add to the simde build for the vector intrinsics which require it. The processor flag would also need to be checked in the dispatch code when selecting the proper binary for the end-user CPU.
