If you're willing to override $(LD), seems you could get around that
additional problem by overriding $(CC) as well:

export CC="$(CC) -m32"
export LD="ld -melf_i386"

I guess we should change that rule to use $(LD) instead of $(CC), and
include $(LDFLAGS) in the rules that build SUBSYS.o. Or maybe there's a
reason they are what they are, I don't know. (SUBSYS.o's are gone in 8.4
anyway)
