I suppose it's because there's no sense whatsoever in including the
SH5 machinery in a sh-elf build.  sh-elf has no support for SH5 in
binutils and simulator, only sh64-elf does.  SH5 is such a different
architecture from earlier SH versions that it barely makes sense to
keep them all in a single bfd_arch.  It only does because one of the
ISAs supported by SH5 happens to be very similar with that used by
earlier SHs, so we can reuse a lot of code.
