Subject: waf: fixed 'make bin/XXX' for the remaining binaries

this fixes 'make bin/smbd' to work correctly with the waf build. It
didn't work before as smbd is actually 'smbd/smbd' internally and we
tried to use the target name 'smbd'. The new approach reads the
symlink to get the right target.

This also speeds up the null build by quite a lot
