Btw, even if these conditions _are_ true, I still don't see how can we
find /usr/libexec/emacs/VERSION/CONFIG/, /usr/share/emacs/VERSION/lisp/
using the fact that Emacs was invoked from /usr/bin/.  Which part of
the code knows about VERSION and CONFIG part and looks for them?  All I
see is that we look for lib-src and etc, but that's only good to detect
that we are being run from the build directory, not from where we are
installed.  What am I missing?
