I'm not in a position to test this, but I think that the problem  
relates to
the fact that neither mv nor echo will change the modified time
stamp on version.h
Make uses modified time to decide what to do next.

you could try changing the if section to read

include/asterisk/version.h: FORCE
        build_tools/make_version_h > $@.tmp
        if cmp -s $@.tmp $@ ; then touch $@; else \
                cp $@.tmp $@ ;  \
        fi
        rm -f $@.tmp
