Patch to fix PR9861 (reprise)

[TJ Laurenzo]

I do now have write access but am a bit short on system resources
needed to actually build and run tests on gcc at the moment.  Since
there has been some time lag between when the patch was approved and
now, I want to reverify it.  I'll see if I can't get that done this
weekend.

Ian: Andrew mentioned that you may be able to offer pointers on the
right way to commit changes to the libiberty bits.  Can this just be
commited to gcc, or does it need to be commited in multiple places to
share with all of the projects.  Your help would be appreciated.
