Only small nolibc updates here. There are two patches in this series. 1. Address Willy's comment about overflow checking in the multiplication operation [1]. This patch supports overflow checking for older compiler versions. Currently, we use `__builtin_mul_overflow()` that doesn't exist in older compiler versions. Instead of using this built-in, use a simple division to check for overflow in the `calloc()` function. 2. The compiler can warn us about wrong `printf` arguments. This patch enables the warnings. Currently, only two functions use this attribute: `printf` and `fprintf`. Hopefully, I can send more updates for 5.21+. Thank you!
