Thomas Weißschuh 1e3c374e9f tools/nolibc: check for overflow in calloc() without divisions ...

On some architectures without native division instructions
the division can generate calls into libgcc/compiler-rt.
This library might not be available, so its use should be avoided.

Use the compiler builtin to check for overflows without needing a
division. The builtin has been available since GCC 3 and clang 3.8.
