Another groff 1.24.0 install datapoint: Devuan

[dvalin--- via discussion of the GNU roff typesetting system and related software]

Have just downloaded groff 1.24.0 and installed it on devuan excalibur.
To make configure complete, I did have to first:
# apt-get build-dep groff
On a debian-derived distro, that's the lowest-effort way to provide all the 
footling things that configure can hang up on.
After that, it was plain sailing.

I would though, change line 66 in INSTALL to:
1. 'cd' to the top directory of the package's tree.
as 'configure' is in fact not in the 'src' directory, as stated.

Now to see if 1.24.0 helps to do stuff. (That isn't working in 1.23.0)
