objtool: Split noinstr validation from --vmlinux
This change adds a --noinstr flag to objtool to allow us to specify that we're processing vmlinux.o without also enabling noinstr validation. This is needed to avoid false positives with LTO when we run objtool on vmlinux.o without CONFIG_DEBUG_ENTRY. Signed-off-by: Sami Tolvanen <samitolvanen@google.com>
