LOG: [clang] Reland NO_LIBCXX test in serenity.cpp (#192638)

The test was first introduced in 934f7950 and then removed in 9c94881f.
The first iteration was depending on the default runtime being
compiler-rt, which isn't true for all bots and thus caused failures:
https://lab.llvm.org/buildbot/#/builders/10/builds/26512

The new version of the test doesn't depend on the compiler runtime.
