Can you share your src/microcode/config.log?

The mechanics.com from a scmutils built on 10.x won't work with 11.x;
you'll need a mechanics.com built on 11.x.  (Sorry about that!  I made
some bad design decisions in the amd64 compiler over a decade ago, and
changed them in 11.x to make essentially all code about 20% faster but
the compiled code is not compatible.)
