No, but as Andre said here earlier, it should be more forgiving when ${S}/waf
is not available or at least give a proper error message instead of dumping a
cryptic exception stack...
In other words, before this waf.bbclass change in oe-core it was handling such
situation just fine and there was a warning "Unable to execute waf --version,
exit code 127". Now it never reaches that code and just throws an exception.
