"Return a matching psABI micro-architecture, allowing optimizations for x86_64
CPUs for compilers which don't allow for more focused optimizing."
;; Matching gcc-architectures isn't an easy task, with the rule-of-thumb being
;; 'Haswell and higher' qualify for x86_64-v3.
;; AVX512F+ for x86_64-v4, AVX+ for x86_64-v3.
