Shouldn't this be more like OPT_SET_INT() on a same variable that is
initialized to "all"? Alternatively you could validate the input
and die when both are given.

Don't you need to clear other variables whose uses are closely tied
to a single repository, like GIT_INDEX_FILE, etc.?
I suspect that explicitly exporting GIT_DIR and GIT_WORK_TREE (and
nothing else) in handle_repo() to the location you discovered before
you run the per-repository command via run_command_v_opt(), might be
a better alternative. The user could be sharing objects in all
repositories by permanently setting GIT_OBJECT_DIRECTORY to a single
place.

I am not very interested in this topic in the first place, but this
does not (at least not yet) sound like a main Porcelain to me.
"all" may be a word other people may want to use to call collections
of things other than "Git repositories", and that use may turn out
to be more useful in general. A name that makes it clear that this
is about "repositories", i.e. along the lines of "git for-each-repo"
or something, would be a better name that does not squat on such a
short and sweet name.
