Adds ATTRIBUTE_UNUSED.

Hi.

At binutils/rename.c.  If neither STAT_TIMESPEC nor STAT_TIMESPEC_NS is defined
get_stat_atime_ns(struct stat const *st) and get_stat_mtime_ns(struct stat
const *st) functions do not use the `st' parameter.  The warning(s) about an
unused variable is treated as an error.

Attached a patch that adds ATTRIBUTE_UNUSED to both of these parameters.  This
began as of commit 985e026451640c880e13827454aa31b7a636d1bc.
