Subject: [PATCH] sysconfig.py: add _PYTHON_PROJECT_SRC

python3 has introduced _PYTHON_PROJECT_BASE which is used for separate B
and S, but it doesn't work when compile Modules, the target python3 runs
python3-native's sysconfig to get srcdir which is the native's, there
would be errors when native's srcdir has been removed, add
_PYTHON_PROJECT_SRC to fix the problem.

Upstream-Status: Pending
