<pre>GNU readelf, when executed with no input files prints the help text. This is
fairly standard behaviour for most tools. llvm-readelf does not - it instead
tries to read the object from stdin. Reading from stdin seems to not be a
particularly useful behaviour for most users, and can also be achieved via a
'-' for the input object. We should change llvm-readelf (and llvm-readobj for
consistency) to do the same as GNU does. This will necessesitate a number of
updates to tests, but otherwise should be fairly straightforward to do (the
updates would be to just use '-' instead).</pre>
