Wasn't this change supposed to fix allmodconfig with KCONFIG_ALLCONFIG
(http://lkml.org/lkml/2013/8/8/573)? Or is there still more to do?
Because I'm still getting:

$ touch empty
$ make KCONFIG_ALLCONFIG=empty allmodconfig
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/kconfig/conf.o
  SHIPPED scripts/kconfig/zconf.tab.c
  SHIPPED scripts/kconfig/zconf.lex.c
  SHIPPED scripts/kconfig/zconf.hash.c
  HOSTCC  scripts/kconfig/zconf.tab.o
  HOSTLD  scripts/kconfig/conf
scripts/kconfig/conf --allmodconfig Kconfig
#
# configuration written to .config
#
$ grep MODULES .config
CONFIG_MODULES_USE_ELF_RELA=y
# CONFIG_MODULES is not set
$
