HV: make: force updating .config and config.mk 

Before checking any given target, make has an additional phase to check if any
included makefile should be updated. This patch enforces running oldconfig in
this phase to update .config and config.mk (if necessary). This ensures that
make gets the correct configurations when executing the given target.
