For me, the <command-line> lines kept getting regenerated in the file x2p/makefile every time I ran make. I had to add perl -i~ -nle 'print unless /<command-line>/' makefile x2p/makefile to the top level Makefile itself before it descended into x2p. 
translators:    miniperl$(EXE_EXT) $(CONFIGPM) FORCE
        perl -i~ -nle 'print unless /<command-line>/' x2p/makefile
        @echo " "; echo "       Making x2p stuff"; cd x2p; $(LDLIBPTH)
+ $(MAKE) all
