that if you dump with a non-ASLR temacs you get a working emacs binary, and
if you don't you don't, although I don't really see why -- perhaps it's
something broken in crtstuff. Closes PR 51654.
Note that pre-ASLR emacs20 binaries not dumped by an ASLR temacs also
blow up in the same way, which doesn't make much sense either, but
undoubtedly it's all connected.
It's not particularly good that we apparently don't have backwards
compatibility for old Emacs binaries because of this, but for the time
being I'm more worried about it working at all.
PKGREVISION++ again, to 22.
