Generaly an executable can be linked to use shared libraries,
or to have the functions it needs from those libraries statically
linked in. Essentially a static image is self-contained and can
be run without reference to anything else. A shared lib
image needs to access the libraries which may be on other
parts of the file systems in order to run.

When you boot single user access to these shared libaries
may not be available. In this case only statically linked
programs can be run. Ergo, this allows you to use the 
tcsh in such modes.
