prep: Add ELF support for -bios
This prepares for switching from OpenHack'Ware to OpenBIOS. While touching the error handling code, switch from aborting hw_error() to fprintf()+exit() and suppress failing without -bios for qtest. Acked-by: Alexander Graf <agraf@suse.de> Signed-off-by: Andreas Färber <andreas.faerber@web.de>
