Don't run new orphan tests on i860 and i960

These targets use the generic ELF support, so don't handle orphans
well.  The patch also updates the orphan doco to reflect this fact,
and deletes some ELF details that don't really add anything.

	* ld.texinfo (Orphan Sections): Mention that not all targets
	handle orphans well.  Delete ELF details.
	* testsuite/ld-elf/orphan-9.d: Don't run for i860 and i960.
	* testsuite/ld-elf/orphan-10.d: Likewise.

 If new output sections are created to hold orphaned input sections,
 then the linker must decide where to place these new output sections
-in relation to existing output sections.  The linker uses a simple
-heuristic to do this.  It attempts to place orphan sections after
