Merge tag 'nolibc-20260412-for-7.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/nolibc/linux-nolibc

Pull nolibc updates from Thomas Weißschuh:

 - Many new features and optimizations to printf()

 - Rename non-standard symbols to avoid collisions with application code

 - Support for byteswap.h, endian.h, err.h and asprintf()

 - 64-bit dev_t

 - Smaller cleanups and fixes to the code and build system
