I think that's the right thing to do anyhow.  That is, use empirical
configure checks for the assembler/compiler features you use, and just
don't try to build the functionality at all if the tools don't support it.
Remediation for old build tools is something we only do for code that is
really essential.  This is an experimental feature that is nothing but
optimization and only usable on hardware nobody has, so it is very far from
it being a priority that it be supported in every build.


Thanks,
