Robert Marko a6210d28db kconfig/lxdialog: fix check() with GCC14
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.

This is a copy of the kconfig code in the kernel (currently 4.17-rc2) tweaked
to suit Buildroot.

To update:
	cp -r /usr/src/linux/scripts/kconfig support/kconfig.new
	cd support/kconfig.new
	# zconf.lex.c and zconf.tab.c needs to be generated by 'make menuconfig'
	mv zconf.lex.c zconf.lex.c_shipped
	mv zconf.tab.c zconf.tab.c_shipped
	rm -rf tests/
	cp -a ../kconfig/patches ../kconfig/README.buildroot ../kconfig/.gitignore .
	quilt push -a
	# Fix any conflict
	cd ..
	rm -rf kconfig
	mv kconfig.new kconfig

Then verify the toplevel targets work:
	config
	defconfig
	menuconfig
	nconfig
	xconfig
	gconfig
	oldconfig
