No.  gcc for cris does not (re-)define TARGET_ASM_FILE_START_APP_OFF, so
the assembler never goes into NO_APP mode.

I can't find any relevant changes in this time frame under config/m68k on
the 3.3 branch.  IIRC m68k-linux never redefined ASM_FILE_START and still
inherits TARGET_ASM_FILE_START_APP_OFF from m68k.h.

Maybe the #APP/#NO_APP switching should be removed and input scrubbing
enabled all the time, given how few targets actually disable it.
