Petr Machata 237188e4d7 elf_begin sets elf_errno for cases that the file is completely unreadable 
- The problem this is trying to solve can be seen for example thus:
	$ eu-readelf -a /
	eu-readelf: failed reading '/': (null)

  With the fix we see a proper error number and get a reasonable error
  message:

	$ eu-readelf -a /
	eu-readelf: failed reading '/': invalid file descriptor
