Bug#851597: gst123: FTBFS if ncurses5-config is not present

[Sven Joachim]

Package: gst123
Version: 0.3.3-1
Tags: fixed-upstream
User: ncurses at packages.debian.org
Usertags: ncurses5-config

The ncurses development packages are going to see a change after the
Stretch release, ncurses5-config will be replaced by ncurses6-config.
Your package FTBFS if ncurses5-config is not present on the build
system.  From my pbuilder log:

,----
| checking for ncurses5-config... no
| configure: error: You need to have ncurses5-config installed to build this package.
| 
| Debian users: aptitude install libncurses-dev
`----

This seems to have been fixed upstream in 0.3.4 by using a pkg-config
based ncurses test instead[1].
