[PATCH v4 34/63] objtool: Rename --Werror to --werror

From: Josh Poimboeuf
Date: Wed Sep 17 2025 - 12:10:37 EST


The objtool --Werror option name is stylistically inconsistent: halfway
between GCC's single-dash capitalized -Werror and objtool's double-dash
--lowercase convention, making it unnecessarily hard to remember.

Make the 'W' lower case (--werror) for consistency with objtool's other
options.
