Bug#576801: libblas-dev: old alternatives system not cleaned after upgrading

[Sébastien Villemot]

Package: libblas-dev
Version: 1.2-6
Severity: normal
Tags: sid

After upgrading from 1.2-4 to 1.2-6, the old alternatives system is still
there (symlinks /usr/lib/libblas-3gf.so and /usr/lib/libblas-3gf.a).

This is due to the fact that the prerm script of libblas-dev 1.2-4 does
not call "update-alternatives --removed" when upgrading.

Not removing the old symlinks makes it difficult for users to understand
how the new alternatives system works.

Best regards,
