With the attached patch, the python test suite runs smoothly on android and
without errors on linux. On android, there are two new failed test cases in
test_sysconfig that I will look into later (in the frame of this issue, I guess
?), but otherwise about the same tests fail that were failing before.
Here are some details about the fix:

This is because _init_posix() in Lib/distutils/sysconfig.py still imports the
native python sysconfigdata module instead of the newly built one for the
target host.
After _init_posix() is fixed, another problem occurs: extension modules are now
built by including /usr/include from the native system and this leads to some
unresolved dlopen references at run time on android. The reason is that
add_gcc_paths() in setup.py calls sysconfig.get_config_var('CC') and this
returns the native compiler instead of the cross-compiler.
So a solution is to set the _SYSCONFIGDATA_NAME environment variable in
PYTHON_FOR_BUILD.
