[mythtv] Building master in F21

[John Pilkington]

I've been running a home-built late qt4 version of master under SL7 
since February, with some forays into current PPA builds under *buntu, 
but it might be good, time etc permitting, to update to a qt5 
self-build.  I have an F21 box that appears to have successfully run 
Stuarta's ansible playbook, a specfile for qt4/SL7 and a current master 
tarball.  Clearly the specfile will need tweaking.  I haven't yet tried 
building on this box and don't know what problems it will show, but is a 
qt5 specfile already out there somewhere?

TIA
