DEP: doc-deprecate BLAS_SRC/LAPACK_SRC

2021-02-06T21:12:49+00:00

Building BLAS and LAPACK from sources in a NumPy build makes
very little sense in 2021. Therefore remove the documentation
for this from `site.cfg.example`, and doc-deprecate it in
`distutils/system_info.py`.

It's hard to properly deprecate and not worth doing, just
de-emphasizing is enough.

BLD, BUG: Fix cblas detection on windows

BLD: compare platform.architecture() correctly

The function returns a tuple of values, of which we need to check the first.

Fixes #17489.

BLD: enabled negation of library choices in NPY_*_ORDER

When users build for a particular order it may be beneficial
to disallow certain libraries.

In particular a user may not care about which accelerated
BLAS library is used, so long as the NetLIB or ATLAS library isn't used.

This is now possible with:

   NPY_BLAS_ORDER='^blas,atlas'

or

   NPY_BLAS_ORDER='!blas,atlas'

Since we may envision more BLAS/LAPACK libraries to the pool, this
will provide greater flexibility as they enter.

A new (local) method is added in system_info.py which removes duplicate
code and allows for easier usage across libraries.

BUG: sysconfig attributes/distutils issue

2020-09-07T21:21:02+00:00

* gh-17223 started the `distutils` modernization
process because of the various upstream stuff
going on (thanks)

* that set of changes caused build issues with NumPy
pre-release wheels + SciPy `master`:
https://travis-ci.org/github/scipy/scipy/builds/725002838

* I was able to patch two separate issues and confirm
that this feature branch restores the SciPy build locally:
1) in one case, `distutils.sysconfig.get_python_inc` was
replaced with `distutils.get_python_inc`, which does not
exist (probably a typo)
2) a bit more serious; even `sysconfig.get_python_inc` does
not appear to exist; the closest match I could find (and
that worked) was `sysconfig.get_path()` with options for
general and platform-specific header paths as needed

* I'm not claiming that these stdlib replacements are perfect
either (the prefix case may still be slightly different?), but
it does prevent the SciPy build break originally introduced
as a start
