kbuild: support simultaneous board configuration and "make all"

This commit fixes two problems: [1] We could not do board configuration and "make all" in one command line. For example, the following did not work as we expect: $ make sandbox_config all Configuring for sandbox board... make: Nothing to be done for `all'. [2] mixed-target build did not work with -j option For example, the following did not work: $ make -j8 sandbox_config u-boot Makefile:481: *** "System not configured - see README". Stop. make: *** [u-boot] Error 2 make: *** Waiting for unfinished jobs.... Configuring for sandbox board... Going forward, we can do $ make -j8 sandbox_config all This is the same as $ make sandbox_config $ make -j8 Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
