Remove the -no-compile-examples configure switch

If '-make examples -no-compile-examples' was specified, sources of Qt's
examples would be installed, but the examples would not be built.

This switch has always been a source for confusion and is only
interesting for distributors, who can just package the examples
directory tree.
