python3: fix for cross compiling
Fixed:
* 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.
* Check cross_compiling when get FLAGS

+Subject: [PATCH] setup.py:check cross_compiling when get FLAGS
+
+Fixed when compile target pythnon3:
+gcc -isystem/path/to/sysroots/x86_64-linux/usr/include \
+ -L=/path/to/sysroots/x86_64-linux/usr/lib
+
+This is incorrect, the native sysroot should not be used by target
+python3.
