This patch fixes the IA64 bootstrap when building libunwind. When using
-fexceptions libunwind will have a reference to __gcc_personality_v0 and
the bootstrap fails, using -fno-exceptions fixes this. This problem
started with r181172, Michael Matz's fix to mark objects death at end of
scope.
Tested on IA64 HP-UX and Linux.
While this change isn't in an ia64 specific file, ia64 is the only
platform affected because no other platform defines LIBUNWIND in order
to build a separate unwind library. So I will go ahead and check it in
if there are no objections.
