lm-header is what package.el itself uses.

I suspect this could be done by using a combination of the
load-file-name hack; see the end of:

(info "(elisp) Multi-file Packages")

combined with lm-header.  To make it even better maybe this could be
done using eval-when-compile so that the bytecode just has a constant.
