[Hartmut Goebel <h.goebel@crazy-compilers.com>]

From: 宋文武 <iyzsong@member.fsf.org>

* gnu/packages/qt.scm (qtbase)[arguments]: Pass docdir, headerdir,
archdatadir, datadir and examplesdir to 'configure'.  Ajdust the
patch-qt_config.prf phase accordingly.
[native-search-paths]: Adjust accordingly.
(qtwayland)[arguments]: New field.
