What I do for this situation is to put something like this in my
Makefile.am:

        DISTCLEANFILES = localedir.h
        localedir.h: Makefile
                echo '#define LOCALEDIR "$(localedir)"' >$@

and then include "localedir.h" separately as needed.

Admittedly this is a bit awkward, but it does the job.
