pgsql: Remove use of lorder and tsort while building static libraries.

Log Message:
-----------
Remove use of lorder and tsort while building static libraries. There's
no evidence that any currently-supported platform needs this, and good
reason to think that any platform that did need it couldn't use the static
libraries anyway --- libpq, at least, has circular references. Removing
the code shuts up tsort warnings about the circular references on some
platforms.
