Description of problem:
The latest qt-devel package places macros.qt4 into /usr/lib/rpm/macros.d

That won't work in F18, rpm does not search that directory.

Version-Release number of selected component (if applicable):
qt-devel-4.8.5-5.fc18.x86_64

How reproducible:
100%

Steps to Reproduce:
1. sudo yum install qt-devel
2. rpm --showrc |grep _qt4_qmake

Actual results:
- no output

Expected results:
- output like: "-14: _qt4_qmake	%{_qt4_bindir}/qmake"

Additional info:
Previous versions of qt.spec correctly checked the fedora version, but in commit b442626fe76a the check has been changed:

This does not seem to work in F18, since the macro file is placed in /usr/lib/rpm/macros.d instead of /etc/rpm/. Because rpm does not search there, the _qt4* macros are not available (e.g. for rpmbuild).

Unfortunately, this causes problems when rebuilding packages...
