Hmmm, I have ...

$ type cc
cc is /usr/bin/cc
$ type clang
clang is /usr/bin/clang

... with a standard MacOS Mojave and Xcode. I do not have any macports or
homebrew packages installed. Do you?

Is something not installed?

In the build directory after it fails is the rtems-tools build tree and under
there somewhere will be a config.log which will have a trace of what waf did and
why it failed to find the header files.
