As I described in the message there is some issue with current ABI approach:

1. LLVM does not have support for AArch64 ILP32
2. GLIBC and Linux are maintained in out of tree branches.

So no current buildbot enabled.

I don't see why not, maybe 32 and 64 to represent the underlying wordsize expected?
