Fix seg fault introduced by ia64 unwind code.

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  When testing the new IA64 unwind code, I missed that it will seg
fault if the target use REL relocations.  I am applying the patch
below to fix this, and also to remove a compile time warning.

Cheers
	Nick
