I think it over. It's no need. For the sub-targets which library is
called, l[hb]z won't be generated too.

: Enable overlapped by-pieces operations
This patch enables overlapped by-piece operations by defining
TARGET_OVERLAP_OP_BY_PIECES_P to true. On rs6000, default move/set/clear
ratio is 2. So the overlap is only enabled with compare by-pieces.
