I used to run into this minor issue frequently when building
development versions of emacs for MIT's campus computer system.
Over time, the build trees would collect a bunch of DOC files, but
it was pretty easy to clean up, and since we were intentionally on
the bleeding edge, keeping multiple versions was occasionally useful.
There is a big problem with that approach, though: only the executable
and the DOC files are versioned. The elisp libraries would immediately
out of sync, and since most of the changes are to lisp files, the
old binary+DOC was of very limited usefulness.
As an aside, these days I follow emacs dev on a macosx system (using
the ns port; the mac port doesn't have this functionality) that
uses a relocatable install, so the entirety of emacs lives inside
a single emacs-only directory tree (Emacs.app). This makes multiple
versions very easy to manage, and I keep at least two independent
emacsen around at all times. It's saved me more than once.
I hope that helps,
