We have hairy configuration method. First configure script uses CONFIG, environment and arguments to produce CONFIG.local and config.h then makefile uses CONFIG, environment and CONFIG.local to produce config.h again. First time config.h can't be generated reliably as config.h target in Makefile is passing MAKEFLAGS and they are unknown at configuration phase. Lets remove this mess by producing final mk/config.mk file and get rid of CONFIG.local. This will also generate full build configuration in one file instead scattering them in CONFIG and CONFIG.local. In next patch scripts/genconfig.py can be removed.
