gcc-4.8: fix ICE of cross-compile for PowerPC e500v2 targets 

* http://gcc.gnu.org/bugzilla//show_bug.cgi?id=57717#c7

  * fix the segfault issue of dd on e500v2 targets
    Since double-float is disabled for e500v2 targets build due to ICE of gcc-4.8.1,
    accordingly %Ld format of sprintf is disabled.
    Address Bug 4910 - [p1022ds]urandom: segmentation fault
