We add libpython to pypa/manylinux. We use the default install locations even though we should really stay in sync with the existing locations and scripts that return LDFLAGS and other flags.
We also violate the manylinux principle by installing some libraries that are not named in PEP-0513.
We build tags of Python that match those already in manylinux. Users can specify which versions to build via the build command.
