Bug#904319: FTBFS when building binary-packages only

[Daniel Baumann]

Package: intel-mkl
Version: 2018.3.222-1

Hi,

thank you so much for packaging intel-mkl, it basically doubles the
performance of our R number crunchers.

However, when locally rebuilding the package I saw that it wants to
check the md5sum of the upstream tarball. This fails when building
binary packages only, which should be possible.

Regards,
Daniel
