Not sure that this is a bug. As Petr Viktorin points out in Comment #4, the reproducer is not expected to work because of the semantics of RTLD_LOCAL.

So the current bpo issue would be related only to a slight inconsistency between the build of extension modules by distutils and those built by the Makefile.

However, it seems that the loader of Android requires that those libraries be explicitly linked against libpython:

* The last paragraph on https://github.com/termux/termux-packages and the related termux issue "Shared library symbols not visible on dlopen()?" (at https://github.com/android-ndk/ndk/issues/201) explain this point.

* The issue I have submitted to pyephem "android cross-build needs the extension module to be linked against the math library" at https://github.com/brandon-rhodes/pyephem/issues/114 confirms this point on Android API level 21.
