PATCH: ldd and LD_DEBUG completions

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

Attached are completions for ldd and the LD_DEBUG environment variable.
The use of the Unix/Type directory for the latter is perhaps
questionable but is probably the best choice. These are based on Linux
and Solaris. I would have checked BSD but the sourceforge compile farm
has gone.

The zsh libraries are not especially cleanly linked by the way. Run ldd
-ur (preferably on Solaris) on them to see what I mean.
