Re: [Linux-ia64] 001117 toolchain release

Why 16 bytes?  The sections only have 8 byte data.  (Technically, the unwind
section has 4 byte data for the 32-bit ABI, but I'm ignoring that for now.)

I added this patch to the FSF binutils sources to fix the problem.  I am not
planning to add a patch for the 001117 release, since this doesn't seem to
be a serious enough problem.

	* config/tc-ia64.c (generate_unwind_image): Call record_alignment
	for unwind info section.
	(dot_endp): Likewise for unwind section.
