Let's rescue some packages!

As Kalev Lember noted on the devel list, several Ada packages still haven't been rebuilt with GCC 5 in Fedora 22. Shall we try to keep them from dropping out? On malkin.scrye.com I could build and install Aunit, AWS, Florist and Templates Parser without any problems. Gnatcoll and Matreshka had compilation errors, but at least the one in Gnatcoll looked straightforward to fix. Thus it looks like most of the packages can be saved. I'm applying for co-maintainership to be able to help. Björn
