Bug#892130: qtchooser: qtconfig doesn't find qt5 version

[Erik de Castro Lopo <erikd@mega-nerd.com>]

Package: qtchooser
Version: 64-ga1b6736-5
Severity: normal

Dear Maintainer,

I run a few Qt apps in the Mate desktop environment. When I run `qtconfig` on the
commandline I get:

    > qtconfig
    qtconfig: could not exec '/usr/lib/qt5/bin/qtconfig': No such file or directory

When I use apt-file to search for "bin/qtconfig" I get:

    > apt-file search bin/qtconfig
    qt4-qtconfig: /usr/bin/qtconfig-qt4
    qt4-qtconfig: /usr/lib/x86_64-linux-gnu/qt4/bin/qtconfig
    qtchooser: /usr/bin/qtconfig

so the error message above from "qtchooser" is pointing to an executable that does
not exist in Debain.
