SMSTOP/SMSTART require the SME arch extension for the assembler. Add '.arch_extension sme' to za-test.S and zt-test.S.
I've got an alternative, more idiomatic fix for this running through my testing - SME is still relatively recent so we can't rely on people's toolchains having it and we should use a .inst instead. The issue was that the toolchain I'm using locally appears to default to a full fat version of the architecture and happily assembled the SMSTART even though we don't have a .inst macro for it like we do with SMSTOP (which is why that didn't error). We only have SMSTART SM and SMSTART ZA.
