The tic command needs to be under the 'install-exec-hook:' target, not
the 'install:' target. Specifying the 'install:' target overrides
everything else, causing the dtterm binary to not be installed on a
'make install'
Liang Chang added utempter support to the dtterm widget in
pre-autoconf CDE. While the code itself was merged, it was still not
"turned on" for autoconf builds.
This commit completes the implementation allowing dtterm on Linux and
the BSDs to be installed without having to be setuid root -- as long
as the libutempter headers and libraries are installed.
Also, restructure some of the dependencies in the lib/tt binaries. We
will link with libtt (which will include libtirpc as a dependency),
and XTOOLLIB - all the right X11 stuff without needing to add it to
every OS. Removed several uneeded OS specializations ("if LINUX",
etc) as a result.
