kconfig: fix 'invalid option' for help option
scripts/kconfig/conf supports -? option to show the help message. This is not wired up to Makefile, so nobody would notice this, but it also shows 'invalid option' message. $ ./scripts/kconfig/conf -? ./scripts/kconfig/conf: invalid option -- '?' Usage: ./scripts/kconfig/conf [-s] [option] <kconfig-file> [option] is _one_ of the following: --listnewconfig List new options --helpnewconfig List new options and help text --oldaskconfig Start a new configuration using a line-oriented program ... The reason is the '?' is missing in the short option list passed to getopt_long(). While I fixed this issue, I also changed the option '?' to 'h'. I prefer -h (or --help, if a long option is also desired). Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
