nios2: fix div64 issue for gcc4
This patch fixes the run-time error on div64 when built with
gcc4, which was reported by jhwu0625 on nios forum. It merges
math support from libgcc of gcc4. This patch is copied from
nios2-linux.
It works with both gcc3 and gcc4. The old mult.c, divmod.c and
math.h are removed.
