This is essentially what it seems the Solaris tools do as well.

But I wonder about the current elf_object_p test.

If the backend data specifies ELFOSABI_NONE, it accepts any OSABI
type.

This seems precarious, at best.

It means that we don't have any protection making sure that only
ELFOSABI_GNU targets accept ELFOSABI_GNU objects.

So, for example, since the Solaris/SPARC target uses ELFOSABI_NONE
currently, it will accept ELFOSABI_GNU objects.

Also, if we start setting ELFOSABI_SOLARIS for Sparc/Solaris targets,
we'll accept those ELFOSABI_SOLARIS objects on targets using
ELFOSABI_NONE.
