Dear Patrick Gerber,

Please fix your git commit log. The first line of a git commit log
becomes the title of the e-mails, so it should have a length no longer
than 80-100 characters. After this first line, leave an empty new line,
and add more details for your commit log.

As Samuel pointed it out, this unfortunately may break a number of
things in Buildroot. They are packages that depend on host-python, and
would only be capable of using an Python 2.x host-python.

Or at least, I would like to have the confirmation that all packages
that depend on host-python continue to build normally when host-python
is Python 3.

That said, some packages are not really clear about this. For example,
Scons uses the Python provided with the distribution, and not the
host-python built by Buildroot.

As you can see, this is not a trivial topic.

Best regards,

Thomas
