HPPA64 .PARISC.unwind entries

Browse Source 
.PARISC.unwind has 32-bit addresses in both 32-bit ELF and 64-bit ELF.
Well, strictly speaking, the 32-bit "start" and "end" fields are
segment relative offsets.  (The 64-bit ABI says so, while the 32-bit
ABI says they are addresses but it appears they are segment relative
offsets in practice.  Likely the 32-bit ABI lacks an update.)

	* readelf.c (hppa_process_unwind): Don't use eh_addr_size to
	calculate number of entries.
	(slurp_hppa_unwind_table): Don't use eh_addr_size here either.
