waf requires that the current working directory be the project root (in
this case ${S} when it is invoked. The check to get the waf version was
being executed as a prefunc for do_configure, which meant it was
executed before the current working directory was switched to ${S}, and
thus would fail with some recipes. Fix this by changing to ${S} before
executing "waf --version"
