Bug#676726: Workaround implemented in atlas 3.8.4-8

[Sébastien Villemot]

Hi,

It seems impossible to elegantly solve this bug without having hooks in
update-alternatives (a wishlist bug is filed for that).

In the meantime, a workaround has been implemented in order to minimize
the incidence of this bug.

Starting from version 3.8.4-8 of Atlas, the Lapack alternative provided
by Atlas has a lower priority than the one provided by Netlib's
reference Lapack. That means that the bug will never hit as long as the
alternatives are left in automatic mode (which is the default).

The downside is that one won't automatically benefit from the
optimizations made by Atlas into Lapack, unless the alternative is
manually modified.

The decision to implement this solution has been made jointly by
Sylvestre Ledru (maintainer), Julien Cristau (Release Team) and myself,
during the Debian Science Sprint kindly sponsored by ESRF, Grenoble,
France.
