kconfig: speed up all*config + randconfig
Drop the chatty mode when we generate the all*config, randconfig configurations. Ths speeds up the process considerably and noone looked at the output anyway. This patch uses the conf_set_all_new_symbols() function just added to kconfig. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
