Translate $ISA as "Instruction Set Architecture" or perhaps processor
feature and favor hook.  On most intel/amd... boxes ISA issues are
transparent so this is not set.  Some folks do get hit by 386/ 486/
586/ 686 differences when they fiddle with hardware in the wrong
compatibility direction.

By setting $ISA an optimized, feature extended or compatible library
could be found first.

Try to not confuse it with the other 500 uses for ISA (like Industry
Standard Architecture. A bus standard for IBM compatibles that extends
the XT bus).
