I added an m4 macro `GROFF_PERL' at `m4/groff.m4'.  It tests whether
there is a `perl' program with version >+ `v5.6.1'.  When there isn't
a suitable `Perl', the `configure' script will break, but
`autoconf/autoreconf' will not report an error because there is no m4 error.

I hope that the configuration parts are still ok so far.
