Error with python 3.7 : Require native threads

[jeromedias86]

I'm in Ubuntu 18.04.5 and working with the branch patched-8
I get this issue when I use python 3.7 or higher from my system :
/usr/include/python3.7m/pythread.h:122:5: error: #error "Require native threads. See https://bugs.python.org/issue31370"

This issue doesn't occur when I use a lower python version (python 3.6.12 works for me)

The problem seems to come from this line where _POSIX_THREAD is unset :

PythonQt/src/PythonQtPythonInclude.h

Line 38 in fae2301

#undef _POSIX_THREADS

If I comment this line all is working for me, but don't know if it's the best solution to fix this issue.

Closing. Support for newer Python versions has been integrated in patched-9 branch.
