Uniformly use MBEDTLS_THREADING_C guards
...
Since the code compiles with MBEDTLS_THREADING_C, not just with
MBEDTLS_THREADING_PTHREAD, use MBEDTLS_THREADING_C as the guard. The runtime
behavior is only as desired under certain conditions that imply
MBEDTLS_THREADING_PTHREAD, but that's fine: no metatest is expected to pass
in all scenarios, only under specific build- and run-time conditions.

That's nonstandard. Instead, convert to an integer.

Add a metatest program

This program can be used to validate that things that should be detected as
test failures are indeed caught, either by setting the test result to
MBEDTLS_TEST_RESULT_FAILED or by aborting the program.
