 We get curious results: `py36-numpy +gcc9` builds under 10.12 and 10.14,
 but not 10.13.  I can't tell whether it's hardware or macOS differences,
 or possibly GCC, or some combination.  System info included as files, but
 here's the top bits:

 10.12 (succeeds):
 {{{
 hw.optional.avx2_0: 0
 hw.optional.avx1_0: 0
 }}}

 10.13 (fails):
 {{{
 hw.optional.avx1_0: 0
 hw.optional.avx2_0: 0
 hw.optional.avx512f: 0
 hw.optional.avx512cd: 0
 hw.optional.avx512dq: 0
 hw.optional.avx512bw: 0
 hw.optional.avx512vl: 0
 hw.optional.avx512ifma: 0
 hw.optional.avx512vbmi: 0
 }}}

 10.14 (succeeds):
 {{{
 hw.optional.avx1_0: 1
 hw.optional.avx2_0: 0
 hw.optional.avx512f: 0
 hw.optional.avx512cd: 0

 Let me know, please, if there's other information which may help.  Thanks
 in advance.
