+Improve detection of CPU features
+=================================
+
+Replace ``npy_cpu_supports`` which was a gcc-specific mechanism to test support
+of avx with more general functions ``npy_cpu_init`` and ``npy_cpu_have``, and
+expose the results via a ``NPY_CPU_HAVE`` c-macro as well as a python-level
+``__cpu_features__`` dictionary.
