PEP3140: ABI version tagged .so files:
https://www.python.org/dev/peps/pep-3149/
There's still one unexplained bit: pypy adds '-' + sys._multiarch()
at the end (looks like 'x86_64-linux-gnu'), but neither py2 or py3 do
Additionally, in older releases of pypy (e.g. build f3ad1e1e1d62
Aug-28-2015), sysconfig.get_config_var('SOABI') returns '' but
shared library still has '.pypy-26' in the name!
So for pypy we try this this variant anyway!
_I_ think Py2 and Py3 _MAY_ start adding sys._multiarch at some time
So, we generate three forms:
1. With sys._multiarch
2. Without sys._multiarch
3. libpath as-is - always tried by self.__openlib anyway
For different versions we try in different order (for efficiency):
Python2 Python3 Pypy
