(I already mentioned, but some apparently missed it or
--hopefully not-- disbelieved it, so let me repeat anyway, that)
I checked arm-linux main trunk, confirming that *no* #NO_APP is
generated at the top of the generated assembly files.

I'm reluctant to accept the list above (except for CRIS and
m68k from previous checking) without checking myself. ;-)
