By the way, it is possible to set $OBJFORMAT (the environment variable) in
a Makefile. This might be an idea for sys/boot/Makefile and
sys/i386/boot/Makefile
Is this worth doing? For example:

This basically causes make to pretend that was appended onto the end of
the command line. It gets set as ${OBJFORMAT} and is exported. Setting
${OBJFORMAT} is not much use in many places because sys.mk has already
made decisions. But it's fine for passing down to sub directories.
DISCLAIMER: I used this ages ago, I don't know for sure if it still
works. I have not tested it.
