* doc/groff.texinfo: Make PDF version compilable with makeinfo 5.x.

makeinfo 5.x handles macro expansion better, which changes the way
how an \LE macro (for a less-than sign) has to be defined.  However,
since we can't be sure that the latest version of `texinfo.tex' gets
used with makeinfo 5.x only, we would have to support both 4.x and
5.x.  No idea whether this is possible at all...  For this reason,
we now simply use @value directly instead of wrapping it into a
macro, avoiding any issues.
