I did another build, with ncuses and tui and without system readline.
FAIL does not reproduce.

--- Comment #2 from Tom de Vries <vries at gcc dot gnu.org> ---
In configure.ac we have:
...
# These are the libraries checked by Readline.
AC_SEARCH_LIBS(tgetent, [termcap tinfow tinfo curses ncursesw ncurses])
...
I didn't have termcap installed (which supplies termcap and curses).
AFAICT, ncurses supplies tinfow, tinfo, ncursesw, and ncurses.
So after deinstalling that, no library is found.
So, I guess this is the behaviour we get when using stub-termcap.o:
...
if test "$ac_cv_search_tgetent" = no; then
CONFIG_OBS="$CONFIG_OBS stub-termcap.o"
fi
...
In rl_redisplay we hit this code:
...
/* If we can move the cursor up and down, then use multiple lines,
otherwise, let long lines display in a single terminal line, and
horizontally scroll it. */
displaying_prompt_first_line = 1;
if (_rl_horizontal_scroll_mode == 0 && _rl_term_up && *_rl_term_up)
...
else /* Do horizontal scrolling. Much simpler */
...
and do horizontal scrolling, even though _rl_horizontal_scroll_mode == 0,
because _rl_term_up == nullptr.

[gdb/testsuite] Fix gdb.base/readline.exp with stub-termcap
When doing a build which uses stub-termcap, we run into:
...
(gdb) set width 7
<b) FAIL: gdb.base/readline.exp: set width 7 (timeout)
...
Since readline can't detect very basic terminal support, it falls back on
horizontal scrolling.
Fix this by detecting the horizontal scrolling case, and skipping the
subsequent test.
Tested on x86_64-linux.
