make install error for SunOS 4.x

["Alan Sparks" <asparks@nss.harris.com>]

The manpage installation uses a 'ln -fs' command to produce symlinks... This
is OK if you are path'ed to /usr/5bin, but the -f option is incompatible
with the standard SunOS command (which means force directory link).

Without changing your path before installation, you will get many usage
clauses from each link installation.

Can an LN definition be added to the make-platform file for SunOS to set the
correct behavior?  I think the correct thing to do is change the hard-coded
"ln -sf" lines in the manpage Makefiles to use ${LN} instead.
