Remove scavenging of read-only space.
*SCAVENGE-READ-ONLY-SPACE*
is always set to NIL
, and it's highly
unlikely any one ever sets it. I (rtoy) haven't done that in decades
at least.
So, remove this static symbol, and remove the C code that tests for this to determine if the read-only space should be scavenged.
This requires a very simple cross-compile to remove the symbol. See boot-2020-04-1.lisp for very simple instructions. We currently on do this for x86 since we can't test on sparc right now.
Update CI to do a cross-compile.
