[Buildroot] [PATCH 0/3] allow to recompile wireless-regdb

[Kurt Van Dijck]

This series adds an option to recompile wireless-regdb.
This became necessary in our product for outdoor use.
In some countries, different regulations apply for indoor
and outdoor use. The precompiled version of wireless-regdb
is appropriate for indoor use only.

For this to work, we compile using python3, and added
host-python3-m2crypto prerequisite in buildroot.

Finally, we patched wireless-regdb for hiding the username
of the build-server.

Kind regards,
Kurt
