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.

[yann.morin.1998@free.fr: add note about upstream kernel]
Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr>
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.

With this, we can trash our probability patch, it's now upstream.
Refresh a few other patches.

Our kconfig code is updated to the version of kernel 3.9-rc2. No major
issues during the migration, except:
* Some conflicts when applying 03-change-config-option-prefix.patch
due to upstream kernel changes.
* The need of adding a new patch, 15-fix-qconf-moc-rule.patch, to fix
the make rule that generates the moc file for the Qt-based
interface.
