If available, use qtchooser to select correct Qt tools
When the Qt directory is specified by --with-qt-dir, the tools are only searched for in the corresponding bin subdir and their full path is retained, so that it is not necessary modifying the PATH and PKG_CONFIG_PATH environment variables to select a custom Qt version. Otherwise, if qtchooser is detected early in the PATH, the generic names are attempted with proper arguments to select the desired Qt version (e.g., "moc -qt=qt5" if --enable-qt5 is specified). Failing all of the above, the generic names with and without proper suffixes (either -qt4 or -qt5) are checked in the PATH. Eventually, a check is performed and a warning is issued if the selected tools do not match the chosen Qt libraries.
