+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.
+
+Upstream-Status: Pending
