Numpy failing to enable CPU features

Compiling Numpy with MSVC entails the following output

INFO: 
########### CLIB COMPILER OPTIMIZATION ###########
INFO: Platform      :
  Architecture: aarch64
  Compiler    : msvc

CPU baseline  :
  Requested   : '+neon'
  Enabled     : none
  Flags       : none
  Extra checks: none

CPU dispatch  :
  Requested   : 'max -xop -fma4'
  Enabled     : none
  Generated   : none

Requesting any permutation off features always return Enabled: none. You can try this with:

python setupy.py build --cpu-baseline="max"

In case you force clang with

python setup.py build --compiler=clang++

Numpy fails to compile as it doesn’t know how to compile with clang on platform NT.

This needs to be fixed as SIMD optimizations seem to be all disabled.
