Does this happen to fix this kind of failure that started showing up a 
week or two ago?

/tmp/ccdAErP7.s:6522: Error: unrecognized opcode `mul a5,a4,a5', 
extension `m' or `zmmul' required

I started chasing it down and concluded it likely wasn't the compiler, 
but couldn't take it further before covid knocked me out.  I'm just 
starting to try and catch up on things today...
