Ross Burton 568d4d7f9c gem5/gem5-aarch64-native: backport a patch to reduce warnings
With Python 3.9 the build produces a huge number of warnings, resulting in a
do_compile log that is 17M long.

Backport a patch from pybind11 upstream to silence this warning.

Subject: [PATCH] Avoid using deprecated API in python 3.9
The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions are
now deprecated and will be removed in Python 3.11. Calling
PyEval_InitThreads() now does nothing. The GIL is initialized by
Py_Initialize() since Python 3.7.
