Reason: 7% tests passed, 92 tests failed out of 99

Most of them fail with:
cstddef:50:10: fatal error: 'stddef.h' file not found

+Subject: [PATCH] Make tests work when clang library is different from system
+ default
+
+If we have found the clang folder, we can resolve the executable from there.
+In my case, I was compiling against clang16, but my system default was clang 14.
+The stacktrace is really confusing and hard to understand. Using the
+absolute path makes the log also better to understand and to reproduce
+the test results.
