bug#48743: 28.0.50; batch-native-compile should produce .elc files as well

[T.V Raman]

1. Large packages that span multiple files can have build-order
   dependencies e.g. files containing macros need to be built and
   loaded when compiling the rest of the package.

   2. At present, jitted .eln files appear to be compiled from the .el
      files, and that misses these dependencies, leading to spurious
      warnings, and possibly incorrect behavior.

      3. Attempting to fix this by using -f batch-native-compile fails
         in one and possibly two ways:

         A. If the Makefile defines its build rules   using .elc and
            .el suffixes, then one needs to first  remove the .elc
            files before  running make in order to generate the .eln
            files. These .eln files  end up in .emacs.d/eln-cache;

B. however if one then rebuilds the .elc files, those are now
            newer than the .eln files, which means the .eln files get
            jitted anyway. That jit run of course produces all the
            afore-mentioned problems.
            

            Suggestion:  have batch-native-compile generate both .eln
            and .elc files -- or alternatively, have the jit compiler
            generate the .eln files from .elc files if the .elc files
            are newer. The latter solution would be nice since it
            isolates package developers from having to think about
            native compilation, and differences between .eln and .elc
            files with respect to warnings and behavior.
