nolibc changes for v6.19

Highlights:

* 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.
