yes, it is. Please see the autoconf.mk build step in the top level makefile: it processes (among other things) the board config file and creates include files to provide the needed symbols for make. It is this mechanism that allows us - for example - to move the CONFIG_SYS_TEXT_BASE definitions into the board config files, even though these are needed in the Makefiles for the linker step.
