[PATCH] Avoid -Wformat-security in in output_die

[Jakub Jelinek]

Hi!

While name will not contain any % characters, because it is what
dwarf_attr_name returns and there aren't attribute names with % in them,
all other spots that call dw2_asm_output_data use "%s", name instead of
name, so I think we should do the same here.

Ok for trunk if testing succeeds?

        * dwarf2out.c (output_die): Use "%s", name instead of name to
        avoid -Wformat-security warning.
