bug#43050: 28.0.50; portable dump file name should respect program-prefix config option

[T.V Raman via Bug reports for GNU Emacs, the Swiss army knife of text editors]

If you configure emacs with the --program-prefix option,
e.g. --program-prefix=native- when building emacs with gccjit support,
the portable dumper file   continues to be named emacs.pdmp, thus
making it impossible to install  both a regular emacs build  and one
with native-comp support.

An easy fix would be for the portable dumper file name to respect
program-prefix

This is already supported.  The only thing that's missing, AFAICT, is
that "make install" should apply the prefix to the dumper file name.
But if you rename the dumper file manually in the same directory where
it is installed, it should work.

There's a patch for that in https://debbugs.gnu.org/42790

People say that using the fingerprint would be better, and it would, but
there isn't a patch for that.

However, that probably isn't enough since by experiment it seems as if
Emacs prefers "emacs.pdmp" to more specific names. So if you have an
Emacs configured without a name transformation and one configured with a
name transformation (and some different options) installed in the same
place, trying to start the second one fails with:

  emacs: could not load dump file "/path/to/emacs.pdmp": not built for
  this Emacs executable

So you can't have two different Emacs installed in the same place,
which defeats the purpose of configure's name transformation options.

Ie this kind of thing fails:

configure --prefix=/tmp/EMACS --without-x --program-suffix=-nox
...
make install
rename installed "emacs.pdmp" to "emacs-nox.pdmp" [1]


configure --prefix=/tmp/EMACS
...
make install


[1] You also have to make a symlink "emacs-28.0.50-nox.pdmp" if you
want to be able to use the binary under the name "emacs-28.0.50-nox"
as well as "emacs-nox".

This whole business seems rather fragile.

I guess putting the fingerprint in the pdmp name is the only proper solution.
Hope someone knows how to do that...

Maybe we should change that preference?  AFAIR, the preference is
there only as the last resort, no?  Or when does that preference make
sense?

If changing the preference for emacs.pdmp isn't workable, you are
probably right.
