bug#8314: 24.0.50; emacsclient -c does the wrong thing when compiled without X

[PJ Weisberg]

I'm reporting this with the emacs snapshot from
http://emacs.naquadah.org/, but the problem exists in Emacs 23 as
well.

1) Build emacs with '--with-x=no'.
2) Start emacs with '--daemon'.
3) From a terminal emulator under X, such as gnome-terminal, with the
$DISPLAY environment variable set, run 'emacsclient -c'.

Expected: Same behavior as when no display is available, which is to
fall back to the tty.
Observed: "Waiting for Emacs..." is printed to the terminal, then
emacsclient exits with nothing else apparently happening.

It DOES fall back to the terminal if the DISPLAY env variable is set to ''.
