[PowerPC]: e500 target can't use lwsync, use msync instead The e500 core has a silicon bug that triggers an illegal instruction program trap on any sync other than msync. Other cores will typically ignore illegal sync types, and the documentation even implies that the 'illegal' bits are ignored. Address this hardware deficiency by only using msync, like the PPC440.
