To simplify the top level makefile it useful to be able to parse
the top level makefile target to multiple individual target, then
put them to the config.h, leave the board config file to handle
the different targets.

Note that this method uses the '_'(underline) as the delimiter when
splits the board make target.

According to the comments from Wolfgang and Scott, I modified
the patch and made some modification over v1:

 - remove the sectence thats puts the splited variables to the
   config.mk, we can use the CONFIG_MK_* in the board config file
   to override the variable in the board config file.

 - change CONFIG_OPT_* to CONFIG_MK_*
