Setting make options in a makefile

Can I create a makefile which will behave as if some options were passed to make executable?

Generally speaking, you can't. But in practice you can rerun your make session with proper options as follows:

ifndef __mk_ready

MAKEFLAGS += --jobs=10
MAKEFLAGS += --no-print-directory

.DEFAULT_GOAL := all

% :
    @$(MAKE) __mk_ready=1 $@

else

# ...

endif # __mk_ready

As far as I know it's not possible to modify e.g. the -j value or add the behaviour of -d run-time in a Makefile. However, one nice workaround is adding a target like this:

debug:
        make -d debugtarget

Now make debug works just like make -d debugtarget. You can even make "debug" your default target and get the same effect with just make.
