one idea:
1) add a dependecy:

geoidx_DEPENDENCIES = builddate-stamp

(Look at the generated, if geoidx_DEPENDENCIES is there, be
sure to add it here, too.)

Rule for the stamp:

builddate-stamp: $(geoidx_OBJECTS)
        generate builddate.c
        compile builddate.o
        then touch builddate-stamp

Yes, with a normal one-time build, builddate.c will be generated and
compiled twice.  But I guess it doesn't hurt too much.

Have a nice day,
