Don't do that.

It renames the file but it does not change the library's SONAME:

$ readelf -d $QTDIR/lib/libQtCore.so.4.8.0 | grep SONAME   
 0x0000000e (SONAME)                     Library soname: [libQtCore.so.4]

When you link an application to a library, the linker will copy the library's 
SONAME to the application's dynamic header:

$ readelf -d $QTDIR/lib/libQtGui.so.4.8.0 | grep QtCore
 0x00000001 (NEEDED)                     Shared library: [libQtCore.so.4]

That's the file that the dynamic linker will search for. So your renaming will 
have no effect: you still need the symlink with the "lib" prefix.

What you really want is:

CONFIG += plugin no_plugin_name_prefix

Plugins don't have sonames.
