I admit this may be be a bit aggressive, but the lang
folder is getting cluttered/filled up with Python, PHP, Perl,
Ruby, etc. packages.

Makes sense to try to group them into per-lang folders.

I took the Pythons.

Python 3.6 comes with some new cross-compilation logic that
generates filenames/paths with arch, abiflags and mach
included (in filename & path).

Problem is that the generated paths/filenames are not
consistent across archs (noticed on x86_64 & ar71xx),
so patch `016-adjust-config-paths.patch` was added
to mitigate this (by removing extra stuff in paths).
