Hehe. printf is funny. -2 is ok for "%u, but $TOO_BIG_POSITIVE
is not ok for %d:

# /usr/bin/printf '%d\n' 9223372036854775808
/usr/bin/printf: 9223372036854775808: Numerical result out of range
9223372036854775807
# /usr/bin/printf '%u\n' 9223372036854775808
9223372036854775808
# /usr/bin/printf '%u\n' -2

I fixed busybox to match this, will be in 1.15.x
