[GIT PULL] nolibc changes for v6.3

[Paul E. McKenney]

Hello, Linus,

Please the latest nolibc changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git tags/nolibc.2023.02.06a
  # HEAD: c54ba4178159e440bea3826d22d43a9d0d94b071: selftests/nolibc: Add a "run-user" target to test the program in user land (2023-01-24 15:35:45 -0800)

----------------------------------------------------------------
nolibc updates for v6.3

o	Add s390 support.

o	Add support for the ARM Thumb1 instruction set.

o	Fix O_* flags definitions for open() and fcntl().

o	Make errno a weak symbol instead of a static variable.

o	Export environ as a weak symbol.

o	Export _auxv as a weak symbol for auxilliary vector retrieval.

o	Implement getauxval() and getpagesize().

o	Further improve self tests, including permitting userland testing
	of the nolibc library.

----------------------------------------------------------------
