Oops, forgot to note that this is only for 68010, and other
systems including m68k are not affected.
Thanks,

Log Message:
Fix broken printf(3) %d output for numbers more than two digits, e.g.,
printf("%d\n", 42) ---> "::" instead of "42"
Our __{,u}modsi3 codes assume that __udivsi3 returns remainder to
%d1 (volatile register). __udivsi3 in libgcc does not, and therefore
mixing them up results in mess.
