Lintian tag information: old-style-config-script (type: pedantic)

Description (from lintian-explain-tags)

The following file is an old style config file, used to retrieve
information about installed libraries in the system. It is typically used
to compile and link against one or more libraries.

Using this kind of system to pass compile file is obsolete and will likely
introduce bugs in a multi-arch system. Particularly, this kind of script
could only belong to a package that is not Multi-Arch.

You should consider to move to pkg-config file and warn your user to not
use this script, and open a bug upstream.

You should also consider to implement this file as a compatibility wrapper
over pkg-config.

After fixing every reverse depends of your package and use pkg-config
reverse depends makefile, you should consider to put this script, as a
temporary convenience of your users, under
/usr/lib/$DEB_HOST_MULTIARCH/$PACKAGE/bin where $DEB_HOST_MULTIARCH is the
multi-arch triplet and $PACKAGE is the package name. You should also
consider to add a NEWS.Debian entry.

Please refer to the pkg-config(1) manual page and
http://sources.debian.net/src/imagemagick/8:6.8.9.9-6/debian/NEWS/ for
details.
