I agree with Lumin here and not Seb -- if and when one adds MKL, it should also be higher priority. That is the point of such a package (which will likely linger in contrib or non-free anyway).
FWIW rather recently I put together a simpler script (not a package). Blog post here: http://dirk.eddelbuettel.com/blog/2018/04/15/#018_mkl_for_debian_ubuntu Repo here https://github.com/eddelbuettel/mkl4deb It's fully workable in the sense that Intel now gives us an apt'able repo which is nice, and our update-alternatives (and ld.conf.d) do the rest.
