Kbuild is supposed to support mixed targets. (%config and build targets)
But "make all" did nothing if it was run with configuration targets.
For example,
$ LANG=C make defconfig all
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
*** Default configuration is based on 'x86_64_defconfig'
#
# configuration written to .config
#
make: Nothing to be done for `all'.
This commits allows "make %config all" and makes sure
mixed targets are built one by one in the given order.
