Make depends use self built clang for darwin

The configure script in hidapi and libsodium tried to find clang in /usr/bin,
even though the correct prefix was passed in. This sets the correct CC flag.
This was previously undetected, because clang and the sdk where
installed in the global environment.

This also fixes a subsequent error, where IOKIT and CoreFoundation are
not found, again for the reason stated above.
