There's a more subtle problem I didn't catch :-(  With this change the
following now fail during bootcheck:

     hard_coded/getopt_test in grade asm_fast.gc
     hard_coded/space in grade asm_fast.gc
     valid/bug134 in grade asm_fast.gc
     warnings/ambiguous_overloading in grade asm_fast.gc

(I think the issue is due to chmod bumping the timestamp on getopt.m
and the stage 2 compiler thinking it needs to rebuild the generated files.)
