Can we have elf64_sparc on sparc-*-linux-gnu*?

If I build binutils with sparc64-*-linux-gnu*, it will produce 64bit
code by default, and gcc will only tell ld to generate elf32_sparc; no
-32 flag is passed to gas, so it will generate elf64_sparc object
files, and ld will complain about them.
But if I build with sparc-*-linux-gnu* (i.e., s/sparc64/sparc/),
elf64_sparc won't be enabled at all. Can't we enable it as an
alternative in this case?
The attached patch is supposed to accomplish this:
