Message-Id: <20250304-nolibc-kselftest-harness-v1-32-adca7cd231e2@linutronix.de>

Subject: [PATCH 32/32] HACK: selftests/nolibc: demonstrate usage of the
kselftest harness
Show how to use the kselftest harness together with nolibc.
This just runs the existing harness selftest by crudely replacing the
regular nolibc-test.c with the harness-selftest.c to get that wired up easily.
In the future nolibc-test can use the harness for itself.
