Could you perhaps elaborate why you think it's not a good idea?

Right, I think I forgot to mention before that we're using
KDE_USE_QT_SYS_PATHS in the packaging scripts which makes triggers a
call which essentially looks for qmake, and in some cases, the qmake
symlink points to a non existent Qt4 qmake which causes
dh_auto_configure to fail.
