This patch fills in the ELF EI_OSABI field. This doesn't matter for most
architectures, but PA-RISC uses the Linux flavour of the ABI (since HPUX
uses the None flavour). Patch courtesy of Randolph Chung.

Someone was a bit too hasty here. Perhaps it might be a good idea to
change this to elf.e_ident instead.

Good catch, thanks:
