coreutils: 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.

+Fix the segmentation fault issue when using dd on e500v2 targets,
+use %f instead of $Lf, since single-float is used for e500v2 due to
