[Python-Dev] support of the android platform

Starting with API level 21 (Android 5.0), the build of python3 with the official android toolchains (that is, without resorting to external libraries for wide character support) runs correctly. With the set of patches described in the patches/Makefile file at [1], the cpython test suite runs[2] on the android x86 and armv7 emulators with only few errors[3]. Those errors are listed with their corresponding error messages, this may give a raw idea of the effort needed to support this platform.
