bug#46256: [feature/native-comp] AOT eln files ignored if run from build tree

[Eli Zaretskii]

I have a question: how do I determine which Emacs binary corresponds
to a particular directory in ~/.emacs.d/eln-cache/ ?

AFAIU, when I make a change in Emacs C sources and rebuild Emacs, the
netive-compiled files will be put in a new directory under eln-cache,
right?  Suppose I later would later like to remove stale binaries --
how do I know which eln-cache subdirectories I can remove at that
time?

TIA
