So IIUC we can compile emacs with both unexec and pdumper support, they
are not mutually exclusive, and we can specify which one to use for the
first dump with --with-dumping.
So yeah I think we have to prevent native compilation to be compiled
with unexec support, even if it's not the way Emacs is dumped the first
time.
