Makefile: Replace flag -DX with -DX= to be supported by IS_ENABLED().
IS_ENABLED works for an empty-string-defined macro.
However, -D options default to define the macro to 1. This CL forces
those macros, such as BOARD_* CHIP_*, CORE_*, CHIP_VARIANT_* and
CHIP_FAMILIY_*, to be defined as an empty string, so that it can
be supported by IS_ENABLED macro.
TEST=use if(IS_ENABLED(BOARD_KRANE)) and see compilation success.
TEST=compares build directory w/ and w/o this CL, and see the .smap
are the same:
ls build/*/*/ec.*.smap | sed -e 's|build/||' | \
xargs -I{} diff -u -a build/{} build.new/{}
BUG=none
BRANCH=None
