Hi, when compiling a program that makes use of the qtconcurrentthreadengine.h
header with GCC 11 compilation failures occur. This issue has been already
reported and fixed upstream, but it will take a lot of time before the fix
lands in a point release of the open source Qt version. You can find the bug
report here: https://codereview.qt-project.org/c/qt/qtbase/+/339417

It's a two line patch, and should be trivial to apply.

I've encountered this issue when building yuzu, a package I'm working on.

Thanks :)

Subject: [PATCH] Remove the unnecessary template parameter from the class specialization

This seems to cause errors when compiling with gcc-11. Although this is
most likely a compiler bug, specifiying the template parameter type in
this case isn't necessary.
