Comment (by mascguy):

 Replying to [comment:24 reneeotten]:
 > I don't see this issue myself; nothing links to {{{py-mkl}}} for
 scipy/numpy. If needed, it
 [https://github.com/numpy/numpy/blob/v1.21.3/doc/source/user/building.rst
 seems] one can supply `NPY_LAPACK_ORDER='!MKL'` as an environment variable
 to avoid using MKL. So that could be added to a variant and/or switched
 off by default. I'll leave it to Michael to decide what to do with it.

 When I tried building with that env var set, it failed with the following:

 {{{
 ValueError: Environment variable 'NPY_LAPACK_ORDER' may not mix negated an
 non-negated items: '!mkl'
 }}}

 As for the linking to `py-mkl`, this is what I see in the NumPy build log,
 when the former is active. (And without using trace mode.)
