Log Message:
-----------
Implement NON_TRANSITIVE case for the tclmatrixd and plplottcltkd
libraries.  When obvious false positives are discounted, ldd -u showed
good results for those libraries in the build tree and for the Tk
examples written in C (i.e., xtk01) in both the build tree and the
traditional installed examples tree.

Build and run tests (using the test_diff_psc and test_interactive
targets in the build tree and the compare and test_interactive targets
in the traditional installed examples tree) produced results without
obvious errors on Debian stable.  However, the latest Linux
distributions such as Fedora or Debian unstable have a linker that
enforces linking rules much more stringently than Debian stable so
additional tests (and likely some fixes) are required before
-DNON_TRANSITIVE=ON will work correctly for the tclmatrixd and
plplottcltkd libraries on those platforms.
