kconfig: scripts/kconfig/zconf.l: add %option noinput
gcc 4.3 correctly determines that input() is unused and gives the following warning: <-- snip --> ... HOSTCC scripts/kconfig/zconf.tab.o scripts/kconfig/lex.zconf.c:1628: warning: ‘input’ defined but not used ... <-- snip --> Fix it by adding %option noinput to scripts/kconfig/zconf.l and regeneration of scripts/kconfig/lex.zconf.c_shipped.
