[Debian-med-packaging] Bug#943828: please don't build against atlas

[Mo Zhou]

Package: altree
Version: 1.3.1-7+b2
Severity: important
Tags: patch

See the recent MBF announcement and #943712

If you think the reference BLAS sucks in terms of performance, it's
recommended to add this for the binary package:

  Recommends: libopenblas-base | libatlas3-base | libmkl-rt | libblas.so.3 ...
