Just do it, it's already supported.  When say "make install", 2
identical binaries are installed, one of them with the name
"emacs-X.Y.Z", the other called just "emacs".  The latter will be
overwritten on the next install, but the former stays.  And each
version has its own share/emacs/ subdirectory.

IOW, it should "just work".
