Basically, this is a chicken-and-egg problem: It is expected that the
just built groff binaries get used to compile the documentation.
However, if you've compiled and installed the groff bundle already for
your build platform, saying

  GROFF_BIN_PATH=/usr/local/bin \
  GROFFBIN=groff \
  make

should do the trick.  Admittedly, this is not documented well (and hopefully
it is not broken :-)

Ideally, the configure scripts disables the build process of the
documentation if it can't find a recent enough groff binary on the
build platform in case of cross compiling.

Any volunteer to fix this?
