Kill aout to elf upgrade path. From an old comment in the makefile:
# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will # update the legacy support for aout. This includes all libraries, ld.so # and boot objects. This part of build should be regarded as # deprecated and you should _not_ expect to be able to do this past the # release of 4.0. You have exactly one major release to move entirely # to elf. Now that we're past 5.0, these aren't needed at all anymore and it is well past its freshness date.
