I am not in favor of this happening. As stated before we can add support via
python. At the moment the builds are separate and waf brings them together, ie
the build stage is not recursive. I see other better way to achieve the same result.

Yes they are. I attach checks.py, place in top dir, then in the rtemstoolkit add:

 import checks

and change the kill test to:

 checks.check_cc_func_name(conf, function_name = 'kill', mandatory = False)

What I provide needs more work but it shows what can be done. Sorry I do not
have time to concentrate on this. A cache could be added to speed up repeated
the tests but you would need to make sure all the arguments are the same.

Note, the test is similar to the method autconf uses.
