 Recent Linux distros may not provide a `python` command by default. This
 breaks building any `waf` based tools such as the `rtems-tools` and
 `rtems-libbsd`.

 Provide support for `waf` builds by check for a suitable Python executable
 and using it to directly invoke `waf`. For example:
 {{{
 /usr/local/bin/python3.7 ./waf configure --prefix=/blah/blah
 }}}
