GCC14 now treats implicit int types as error so when check() from
check-lxdialog.sh is called to check whether we can link against ncurses
it will fail silently and the help text indicating to install ncurses is
printed.
However, this is not due to missing ncurses but once the stderr redirect
to /dev/null is removed we can see the root cause:
<stdin>:2:1: error: return type defaults to ‘int’ [-Wimplicit-int]
So, in order for menuconfig to work with GCC14 lets just specify the
return type of main() as int.
Npte that the upstream kconfig in the linux kernel source tree no longer
carries or uses the check-lxdialog.sh script since commit 1c5af5cf9308
(kconfig: refactor ncurses package checks for building mconf and nconf),
so there is no commit we can backport to our kconfig copy.

buffer of fprintf().
Normally, we want changes to kconfig to be reflected by patches in
support/kconfig/patches. This makes it easier to resync with upstream
kconfig. However, in this case, everything that is changed here is
already changed completely (and differently) upstream, so there is no
added value in keeping the patch.

We are using empty CONFIG_PREFIX_. This results in false positive match
for comment lines when merging config fragments.
To avoid false positive reports, we use separate sed expressions and
address comment lines explicitly.
This is actually is in the Linux kernel mainline (v4.20-rc2):

Buildroot's "make nconfig" command stopped working a while ago on
Gentoo systems. Running the command would result in a crash.
The issue is caused by lxdialog's cflags which are also used to build
nconfig; It would detect *ncursesw* and turn on WIDECHAR support --
but the Makefile would still link to plain *ncurses* while building
nconfig (which was built without WIDECHAR support).
This would cause a crash after using *wattrset* on a WINDOW instance.
WIDECHAR *wattrset* would try to set the _color member in the WINDOW
struct which does not exist in the NON-WIDECHAR ncurses instance. It
would end up clobbering data outside the struct (usually _line entries).
An upstream patch fixes the issue, so we're applying it to Buildroot's
kconfig.

This makes "make menuconfig" also work on systems where ncurses is not
installed in a standard location (such as on NixOS).
This patch changes ccflags() so that it tries pkg-config first, and only
if pkg-config fails does it go back to the fallback/manual checks. This
is the same algorithm that ldflags() already uses.
[This patch is already applied upstream (is part of linux v3.18):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be8af2d54a66911693eddc556e4f7a866670082b
I'm adding this instead of doing a full upstream kconfig sync because
there was a conflict in one of the Buildroot kconfig patches (against
linux 3.18-rc1), which I was unable to resolve. Just drop this patch next time
Buildroot kconfig is synced against upstream.

In case a menu has comment without letters/numbers (eg. characters
matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *),
hitting space will cycle through those comments, rather than
selecting/deselecting the currently-highlighted option.
This is the behaviour of hitting any letter/digit: jump to the next
option which prompt starts with that letter. The only letters that
do not behave as such are 'y' 'm' and 'n'. Prompts that start with
one of those three letters are instead matched on the first letter
that is not 'y', 'm' or 'n'.
Fix that by treating 'space' as we treat y/m/n, ie. as an action key,
not as shortcut to jump to prompt.
