There seems to be a convention that info files shouldn't be split.  Or
is there?  I don't see it in pkgsrc, but it seems to be partly adhered
too.  It really seems to be silly to split files into 50k chunks;
guile-library.info (wip/guile-lib) is 80058 bytes as one file, and it
was 3 chunks - directory, and then two files.   So I patched
--no-split into the Makefile.  I guess the alternative would be to
list all 3 info files in Makefile

I wonder if the makeinfo wrapper should have --no-split instead of
the current:

exec /usr/bin/makeinfo  --split-size=50000 "$@"

with a MAKEINFO_SPLIT variable that avoids that for cases when the
packages build/install scheme is fixated on doing it this way.

In the wip/guile-lib case, the upstream source only installs the
primary info file.
