math/py-numpy: add SIMD options
Per the 2.4 release notes, the default/minimum baseline for compiled
optimisations on amd64 and i386 is increased to the v2 microarchitecture.
Thus, those using CPUs without the full feature set from v2 will
encounter SIGILL when running numpy with the default/minimum baseline.
Add option to disable compiled optimisations, relying entirely on
dispatched code paths when available and applicable. Not recommended
except for very old CPUs. Also add native option.
