I think you might be referring to Mike Frysingers fix to correct a problem 
with the generation of mom-pdf.pdf:-

commit 290eaaac6cfc33856cd683838accc72ccf3e5a84
Author: Mike Frysinger <address@hidden>

    Fix parallel build with gropdf and mom examples.
    
    The `contrib/mom/examples/' directory uses the helper script from
    `src/devices/gropdf/'.  Currently though, parallel builds might fail
    like so:
    
      ...
      make[2]: Entering directory `.../groff-1.22.2/contrib/mom'
      <groff command> examples/letter.mom >examples/letter.pdf
      <groff command> examples/mom-pdf.mom >examples/mom-pdf.pdf
      /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or 
directory
      make[2]: *** [examples/letter.pdf] Error 127
      /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or 
directory
      make[2]: *** [examples/mom-pdf.pdf] Error 127
      make[2]: Leaving directory `.../groff-1.22.2/contrib/mom'
      make[1]: *** [contrib/mom] Error 2
      ...
      make[2]: Entering directory `.../groff-1.22.2/src/devices/gropdf'
      sed -f .../groff-1.22.2/arch/misc/shdeps.sed \
          -e "s|@VERSION@|1.22.2|" \
          -e "s|@PERLPATH@|/usr/bin/perl|" ./pdfmom.pl >pdfmom
    
    The top level makefile tries to account for this in general with
    OTHERDIRS, but looks like `src/devices/gropdf/' was added to this
    variable (which holds `contrib/mom/' too) because gropdf installs a
    shell script, and the other prog vars require it to be a dir of
    things to compile.

    * Makefile.in (SHPROGDIRS): Declare.
    (PROGDIRS): Add $(SHPROGDIRS).
    (OTHERDIRS): Delete src/devices/gropdf.
    ($(SHPROGDIRS):): Add to existing rule.
    ($(OTHERDIRS):): Depend on $(SHPROGDIRS).

I'm not sure whether Bernd's amendment affects this, the parallel build 
problem was intermittent, depending on the speed of the server, number 
of parallel streams, etc..
