Without native-compilation Emacs doesn't need to look for and find
the *.eln files, so it's a small wonder you don't see the problem.

Emacs with native-compilation supports relocatable
installations only if the relation between the directory with the
binary and the directory with the *.eln files is according to the
relation between BIN_DESTDIR and ELN_DESTDIR.  So if you want a
relocatable installation, you will need to play with the values of
those two Make-time variables to suit your needs.  If you use absolute
file names, moving the files will break the installation.
