Pull nolibc updates from Thomas Weißschuh:

- Preparations to the use of nolibc in UML:
- Cleanup of sparse warnings
- Library mode without _start()
- More consistency when disabling errno

- Unconditional installation of all architecture support files

- Always 64-bit wide ino_t and off_t

- Various cleanups and bug fixes

tools/nolibc: add the more portable inttypes.h

It's often recommended to only use inttypes.h instead of stdint.h for
portability reasons since the former is always present when the latter
is present

tools/nolibc: add the more portable inttypes.h

It's often recommended to only use inttypes.h instead of stdint.h for
portability reasons since the former is always present when the latter
is present, but not conversely, and the former includes the latter. Due
to this some simple programs fail to build when including inttypes.h.
Let's add one that simply includes nolibc.h to better support these
programs.
