O= doesn't work as it would (currently) break make-3.80.

Specifying multiple MAKECMDGOALS, i.e. both config and non-config ones
doesn't work since we cannot skip-makefile anymore (would brake
make-3.80), so we cannot guarantee that the (now ditched) second
invocation of make sees all stuff it needs for this to work.
Consider that we have to deal with:
-) completely empty builddir
-) only .config in builddir
-) .....
-) fully setup builddir

Supporting all these variations while trying to be backward compatible
to broken/non-feature complete binaries of make(1) is doable and there,
but if you want to also throw in mixed target-goals for each of the
variants above, it gets really cumbersone.

mkdir /obj/ ; cd /obj
make -f /src/busybox/Makefile defconfig
make

works for me. See INSTALL
