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
sections of the same attribute, such as code vs data, loadable vs
non-loadable, etc. If no sections with matching attributes are found,
the orphan section is placed at the end of the file.
For ELF targets, the attribute of the section includes section type as
well as section flag.

linker attempts to place orphan sections after sections of the same

sections with matching attributes are found, or your target lacks this
support, the orphan section is placed at the end of the file.
The command line options @samp{--orphan-handling} and @samp{--unique}
(@pxref{Options,,Command Line Options}) can be used to control which
