Remove ld.conf as it produces conflicts on systems with Qt installed

[tholewebgods]

Adding the bundled Qt library to the LD path through ld.conf leads to errors with systems which depend on another version of Qt. In fact it caused errors with Fedora 17 builds and KDE.

Actually I've still created a patch. It replaces the wrong RPATH (which is pointing to the build location in rpmbuild/BUILD by a replative path pointing to the library directory).

I'll submit a pull request these days.

Finally pushed: https://github.com/tholewebgods/phantomjs-rpms/tree/dev/gh-8

I'd suggest everyone to test the final .rpm.
