It is able to do like glibc, defining __WORDSIZE for all of platforms and using "unsigned long int" to define uint64_t when __WORDSIZE is 64bits, but here uses a simpler solution: nolibc always requires %lld to match "unsigned long long", for others, only require %lld when word size is 32bit.

As suggested by Thomas, defining INT_MIN/INT_MAX for nolibc can remove the including of limits.h, and therefore no above error. of course, the other libcs still require limits.h, move it to the right place. The LONG_MIN/LONG_MAX are also defined too.
