CHECK_C_COMPILER_FLAG is only testing the compiler flag - but the error
here looks like an issue during linking ... so maybe that's the
reason why the check is not working as expected here?

ENABLE_ASAN is set to 0 by default, so I'm a little bit surprised that
this is causing trouble here ... did you enable it by accident? If so,
setting it to 0 should fix the issue, hopefully.
