start with bbdb-site.el.in, process it into bbdb-site.el solely at make time
tweak bbdb-site.el.in to bbdb-site.el generation process

Use a more symmetric and robust token for where the real tex directory
belongs in lisp/bbdb-site.el.in

Use "sed -e", which is POSIX, instead of "sed --expression", which ain't.

Add appropriate automake magic to cause bbdb-site.el to be generated

"required" by other lisp source files, and to be included in the
distribution tarball.
allow for POSIX date command in timestamp determination
