I think that is a bug.

Makefile seems not to have a separate rule for the file
'emacs.pdump'.  It treats that as an aspect of 'emacs'.  Thus, the
'emacs' rule should write 'emacs.pdmp' correctly too.

I tried 'make -k' just now.  It did write 'emacs.pdmp'.

Then I deleted 'alloc.o' and then 'make -k'.
It loaded up and dumped, writing 'boostrap-emacs.pdmp'.
Then it loaded up and dumped again, writing 'emacs.pdmp'.

That was not necessary.  Once should have been enough.

The reason I omit it is that this was, in the past, a way to avoid
rebuilding stuff I didn't need to rebuild.  Perhaps it was to avoid
recompiling Lisp files (which takes a long time so I always chose
manually what to recompile).  I don't remewmber for sure.

The second dump step is not a big annoyance for me.  On my rather old
machine, chosen to run Libreboot, it takes less than a minute.

But it still seems like an error that the 'emacs' target does not
deliver a working 'emacs'.
