From: Josh Poimboeuf jpoimboe@redhat.com Date: Mon, 15 Jan 2018 08:17:08 -0600 Subject: objtool: Improve error message for bad file argument

From: Josh Poimboeuf jpoimboe@redhat.com

commit 385d11b152c4eb638eeb769edcb3249533bb9a00 upstream.

If a nonexistent file is supplied to objtool, it complains with a non-helpful error:

open: No such file or directory

Improve it to:

objtool: Can't open 'foo': No such file or directory
