It is basically impossible to provide a single binary build that works even on all "reasonably modern" distros (however that might be defined). We have seen that over and over again, and that's why it was decided a longer time ago to use Ubuntu as a reference platform. (Even providing a binary package that works through multiple Ubuntu versions has its trickiness as we've seen in the past.)

Btw, creating a distributable Qt Creator 7zip should be as easy as 

qmake -r CONFIG+=release QTC_PREFIX=/qt-creator-2.8.0 && make && make -j1 docs install install_docs deployqt bindist

if you feel like creating binaries for some specific Linux distribution (and version of that distribution).
('deployqt' optionally if you are not using a system installed Qt from the distribution or want Qt bundled in any case)
