Trying to update qt5 to 5.15?

Please and thank you! A bit problematic that the current one is a build 
from about 2017. I have a doubt on how reliable it can be at this point 
with potential C++ ABI changes under the hood. I gave that a look not 
long ago.

First you have a long list of cygwin-specific patches that are there 
presumably to have the thing just build. Some might need to be dropped, 
and some new ones might need to be added (good luck with that part). I 
know a thing or two about Qt itself but nothing about its bespoke build 
system.

Then I tried to just rebuild 5.9. I was greeted early on by a header 
problem, not too exotic to fix it, and then it was a bunch of errors 
where it couldn't find a long list of libraries, even though they really 
are there (jpeg, png, sqlite, etc.). At that point I said "ok another time".
