Description of Problem:
the symlinks to moc are setup suboptimal

Version-Release number of selected component (if applicable):
qt2 & qt3 with moc2 and moc3

How Reproducible:
install both components

Steps to Reproduce:
1. install moc of qt2
2. install moc of qt3
3. do a "ls -l /usr/bin/moc*"

Actual Results:
moc -> ../lib/qt3-gcc2.96/bin/moc
moc2 -> ../lib/qt2/bin/moc
moc3 -> moc

Expected Results:
moc -> moc3
moc2 -> ../lib/qt2/bin/moc
moc3 -> ../lib/qt3-gcc2.96/bin/moc

Additional Information:
I think the "moc" symlink should point to the default  (either moc2 or moc3)
and the "moc3" must always point to a moc 3 release.
Consider this as a cleanup in the tools system.
