feature/native-comp emacs: could not resolve realpath of "emacs": No such file or directory

[wilde]

Hi,

The current branch head of the native-comp branch produces an emacs
which after "install" yields the following error when run from $PATH
(say with out the path given explicitly):

 % emacs
 emacs: could not resolve realpath of "emacs": No such file or directory

whereas e.g.:

 # /usr/local/bin/emacs

works as expected.

This is _not_ related to my tests on NetBSD, it happens on GNU/Linux
just the same...

I strongly suspect this is related to:

commit 0c1fc9d581ad64efc96c1efccbb4d057796ef807
Author: Andrea Corallo <akrl@sdf.org>

    * Fix native-comp startup for symliked binary (bug#44128)
    
            * src/emacs.c (real_filename): New function.
            (set_invocation_vars, load_pdump): Make use of.

cheers,

sascha
