So, how it was working: 1. build-as was declared with $$(1) and $$(2) which were expanded on entering the submake; 2. function $(call build-as,...) performed the second expansion of build-as. Cons: build-as works only in sub-makefile, no sub-sub-makefile, no upper/top makefile. Simplify this by single $(1). Then build-as variable will be used _only_ in makefile, not in sub-makefiles. This is for now fine, as each file, that calls $(MAKE) with $(build)=dir or $(call build-as,makefile,dir) will include main.mk from NMK, which has build-as definition (from include.mk). In the future, we'll get rid of $(build) and $(build-as) workarounds as finally switch to building from a global makefile.
