Works for me. I
  - took groff git master
  - added pkg.m4 to m4/ to avoid a broken 'configure' later,
  - added an initialization of MOSTLYCLEANDIRS in Makefile.am,
  - ran
    ./bootstrap --no-git --gnulib-srcdir=$GNULIB_SRCDIR --skip-po
    where $GNULIB_SRCDIR references gnulib git master
  - ran
    ./configure
    make
and there is a 'grodvi' built by 'make'.

$ grep FCLOSE config.status
