And I also noticed that the Solaris ELF backend explicitly avoids
using ELFOSABI_SOLARIS because doing so would preclude linking with
what all current Solaris/SPARC objects have, which is ELFOSABI_NONE.

This really puts a pickle into the idea to conditionalize section type
handling upon the OSABI.
