fix Xtensa ld testsuite failures

[Bob Wilson]

I've committed this patch that H.J. suggested to fix the ld testsuite failures 
for Xtensa targets.  It took me a while to figure out that the place_orphan hook 
was only being used to work around a problem in a very old version of binutils. 
  Linking with -r had been causing the order of orphan sections to be reversed, 
which was apparently a problem with an Xtensa port of VxWorks.  I don't know 
when that was fixed, but it doesn't happen anymore on mainline.  I verified that 
with this patch all the ld tests pass for an xtensa-elf target.

Thanks, H.J.  You saved me more time with this patch than I spent last week 
trying to figure out if the failures were expected.  I'm sorry for giving you a 
hard time about that.
