Oh we did, I am sorry.

I am not sure if you have, I have not tested it.

The way rtems_waf works is due to the paths passed to the tool check? My reading
of Hesham's change is only the env path is checked for clang and this is what I
am questioning, i.e. does the --prefix, --rtems-tools etc work with clang just
like gcc?

I think we should be consistent what ever the specifics are and this should
before across different packages and for tools within a package.
