Phew, there was still a _lot_ of dependencies missing.  Even without
repacking for every iteration it took hours just to collect them all.

Here you meant qtbase-QTBUG-81715.patch.

Actually only two failed, with fairly clear error messages.  Figuring
out how to disable them took some time though.

I did not look very closely into what caused the failures, as one of the
first hits on a web search was that Debian disables the exact same test:

 https://ftp-master.debian.org/new/qtwayland-opensource-src_5.14.2-1.html

So we're in good company, at least.  :-)

Nit-pick: colon after the [section].

I fixed these issues and typos for you.

We both forgot to mention this part in the commit message though!

I preserved this comment.

Remember to delete patches from git as well as gnu/local.mk too.  Fixed!

I finally pushed this as 883d0484ddcf3b9f3ff8bd8e6de70627201f2763.

However, qtwebengine is not finished building yet and may still be
missing some dependencies.  I'll fix any remaining issues tomorrow.

Thanks a lot for the effort here, and sorry for the delay!
