Could you check that this condition is met by adding an echo debug in
there?

And what does your $(LINUX26_DIR)/.config look like afterwards? Is EABI
set in there? If so, we'll need to find out why. Could be that there
have been changes in the Linux kernel config which cause EABI to be set,
depending on other config flags, but I don't have a solution at hand
currently. Shouldn't be too hard to figure out, though.
