----------------------------------------------------------------
nolibc changes for v6.16
Highlights:
* New supported architectures: m68k, SPARC (32 and 64 bit)
* Compatibility with kselftest_harness.h
* A more robust mechanism to include all of nolibc from each header
* Split existing features into new headers to simplify adoption
* Compatibility with UBSAN and it is used in the testsuite
* Many small new features focussing on usage in kselftests
