So about this, as a middle ground, would it be okay if I put

``CC=clang LLVM_IAS=0`` (LLVM >= 20)

In the documentation, in a similar manner to the s390x entry?
I know that LLVM 20 is still a couple months away but those commits will
likely be released with that version, and since it also tells people
to not use a version that is too old, I think it should be okay (?)
