Merge tag 'nolibc-20251130-for-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/nolibc/linux-nolibc

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
