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 Change-Id: I96e2aa1cb5f3369e5e445a674595a9234f26707a Signed-off-by: Yilun Lin <yllin@google.com> Reviewed-on: https://chromium-review.googlesource.com/1627840 Commit-Ready: Yilun Lin <yllin@chromium.org> Tested-by: Yilun Lin <yllin@chromium.org> Legacy-Commit-Queue: Commit Bot <commit-bot@chromium.org> Reviewed-by: Jett Rink <jettrink@chromium.org> Reviewed-by: Jack Rosenthal <jrosenth@chromium.org> Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org>
