I wonder when we'll have to standardize /libexec/<arch>/ to support
multiple architectures for things like ld-elf.so.1.  It used to only
be a concern for those rare people running diskless over multiple
architectures, but the case of i386 binaries on amd64 is a little
more common.

On the other hand, if ld-elf.so.1 is fairly unique in this
concern, it might be simpler to rename it to:
    ld-elf-{i386,amd64,ppc,...}.so.1
