[PATCH] fix math/py-scipy linker error on CentOS 7

["Dr. Thomas Orgis" <thomas.orgis%uni-hamburg.de@localhost>]

Hi,

I had this weird linker error, probably relating to my introduction of
BLAS linker flags, trying to build py-scipy. The issue is more general,
though, and there is an upstream patch that is part of the current
release.

Please consider importing the attached patch (also part of the
collection at
http://src.rrz.uni-hamburg.de/extra/pkgsrc-patches/2019Q1/) to the
2019Q1 branch. The version in trunk should just be updated to 1.2.x, I
presume.


Alrighty then,

Thomas
