Dependencies for setdef.h were broken by removing ioconf.o from ${OBJS}.
Previously, any change in the configuration resulted in a change to
ioconf.c, so setdefs.h got rebuilt. Now, removing whole drivers doesn't
change anything in ${OBJS}, so the old setdefs.h gets used and the wrong
amount of space is allocated for some linker sets. This bug cost me a
few hours when I tried removing console drivers in order to debug the
console initialization bugs.
This quick fix also backs out rev.1.180:
diff -c2 Makefile.i386~ Makefile.i386
