Bug 1281854

Description of problem:
-----------------------
If I configure, build & install a package with checkinstall from updated github sources and previous built & install have already been performed with older sources, many files are missing from the deb package.

Dist-clean would allow me to start the process from scratch each time some sources are modified to build a deb package with all the necessary files.

Version-Release number of selected component (if applicable):
------------------------------------------------------------
N/A

Steps to Reproduce:
-------------------
1. update local github clone with latest sources
2. export GI_TYPELIB_PATH=/usr/lib/girepository-1.0/
3. export LD_LIBRARY_PATH=/usr/lib/
4. python setup.py configure
5. python setup.py build
6. checkinstall -D --install --pkgname="virt-manager" --pkgversion="1:1.2.1" --pkgrelease="10" --pkgarch="amd64" --maintainer="manciot.jeanchristophe" --requires="libosinfo-1.0-0,libvirt-bin,libvirt-glib-1.0-0,python-libvirt,gconf2,librsvg2-common,python-dbus,python-gi,python-gi-cairo,python-gobject,gir1.2-gtk-3.0,python-libxml2,gir1.2-vte-2.91,dconf-gsettings-backend,dbus-x11,gir1.2-gtk-vnc-2.0,gnome-icon-theme,python-urlgrabber,python-ipaddr,python-requests" --include="files-to-be-included-in-the-package.txt" --exclude="/usr/share/icons/hicolor/icon-theme.cache" python setup.py install
