2023-08-02selftests/powerpc/ptrace: Explain why tests are skippedBenjamin Gray
Many tests require specific hardware features/configurations that a typical machine might not have. As a result, it's common to see a test is skipped. But it is tedious to find out why a test is skipped when all it gives is the file location of the skip macro. Convert SKIP_IF() to SKIP_IF_MSG(), with appropriate descriptions of why the test is being skipped. This gives a general idea of why a test is skipped, which can be looked into further if it doesn't make sense.
