It's broken because it has a pointer to the non-contrib libreadline,
which no longer exists.

It works here because my bsd.info.mk is a little different and the error
leaks out of a pipe.

contrib/gdb is not actually used.  It contributes a measly 24MB of the
75MB of bloat that came when we started using contrib.

No, the Makefile forces an include of ../faraway/lib/libreadline/doc where
rluser.texinfo was, but the version of rluser.texinfo that was there is
now in contrib/libreadline (perhaps actually a later version :), and of
course contrib brings it in all other gnu software that uses it (only
gdb so far).  The rluser docs for gdb should come from libreadline and
not from gdb, since the version actually used is the one in libreadline.
