[PATCH v2] sb: Add support to search for a suitable version of python.

Wed Oct 24 07:29:57 UTC 2018

Hi Chris,

thanks for your answer. I said yesterday: "it worked fine before commit
13f4c379997b53b204d8534d198da2fa35dd5630" that was actually not true.
The first part worked fine but lateron the GDB build failed. I solved
that issue by reverting even further back.

Your patch works well for the first part:

I asked me that as well, i knew this question would come :D I don't know
but i think this is standard. The Archlinux-Wiki says:

Any program requiring Python 2 needs to point to /usr/bin/python2,
instead of /usr/bin/python, which points to Python 3.

Best,

Malte
