selftests: kselftest: Fix build failure with NOLIBC
commit 16767502aa990cca2cb7d1372b31d328c4c85b40 upstream. As Mark explains ksft_min_kernel_version() can't be compiled with nolibc, it doesn't implement uname(). Fixes: 6d029c25b71f ("selftests/timers/posix_timers: Reimplement check_timer_distribution()") Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20240412123536.GA32444@redhat.com Closes: https://lore.kernel.org/all/f0523b3a-ea08-4615-b0fb-5b504a2d39df@sirena.org.uk/ Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
