If you tell that they are necessary for Clang tests, let's first fix the Clang tests so that they won't be necessary.
They build successfully and pass the tests (apart from the three leak-detection that you should have disabled now). So, I'd rather keep them, so that other people can progress the support on ARM (and I'll be building it regularly and will get a warning if they regress).

Regardless, Clang should be fixed to not automatically assume rt == asan.
