This adds the new `printf_long_long` module that can be used to enable printing of `long long` and `unsigned long long`. This has been implemented for `mpaland-printf`. In addition, this module is a default module for 32-bit and 64-bit systems if `mpaland-printf` is used, 64 bit support is not too expensive for them. (And on 64-bit systems support for long long is needed for support of `%p`, which is pretty basic.) This is mainly useful for MSP430, where otherwise `mpaland-printf` would require more memory than newlib's implementation.
