And in configure. Itʼs not clear to me what the various combinations
of --with-dumping and --with-pdumper are supposed to see (see below).

./configure --with-dumping=unexec --with-pdumper=no && src/emacs -Q
# uses unexec, doesnʼt support pdump. OK

./configure --with-dumping=unexec && src/emacs -Q
# uses unexec, doesnʼt support pdump. OK

./configure --with-dumping=unexec --with-pdumper=yes && src/emacs -Q
# uses unexec, supports pdump. Runs OK. What does 'supports pdump'
mean in this context? That we'll try to load a dump file even though
we've been built with unexec?

In any case, the old unexec code looks like it still works on my
system.
