The place exists where CFLAGS definition starts, there is CFLAGS :=
$(subst -finit-priority,,$(CFLAGS)) in packages/pkgconf/rules.mak. So,
it seems for me that build the same as the below can be used as well

ecosconfig new <target>
ecosconfig tree
make CFLAGS=-D__ECOS__

But, it seems, you are right, it is better to fix main definitions in
the rules.mak.
