Well, the osabi sniffer doesn't say that it's a corefile, it just says 
it's a HPUX ELF file. As for whether "elf64-hppa" means hpux, currently 
bfd/elf64-hppa.c only supports two targets, hpux and linux, and linux is 
"elf64-hppa-linux". I know this is not very nice. Do you have any other 
suggestions?
