You can upload the patch directly to our change review system. See

Indeed. 

See https://codereview.qt-project.org/85118.

Scheduled to be fixed for 5.4.0. We don't really maintain the feature system, 
since the combinations are just too many. So YMMV.

If you have a quick fix for this, it can be added for 5.3.x. But you really 
want the change above, so Qt won't try to link to PCRE.
