Right, ok, this is true for compiler-rt, but not necessarily other runtime libraries.

There is an open discussion if we should assume compiler-rt is the default and use what we have, but this is a different issue.

If the call to `__multi3` is there by accident (leaked from other target's default), then it's ok to remove it. If not, we may need some more complex solution.

@compnerd @joerg @t.p.northover @srhines, do you know of any Arm32 runtime library that implements 128-bit maths with Clang?

I think Android does, so perhaps we can add a condition there on `AndroidEABI`?
