Assuming your semantic is that of BSD make: "assign unless set" [*],
I can see how this help in
if COND1
foo = mumble
endif
if COND2
foo = blurgle
endif
foo ?= else
But I fail to see how you'd use this to override a default
value whose definition has been included from elsewhere.
(Unless inclusions of fragments defining default variables are
done at the end of Makefile.am -- but this raises a few other
issues.)

[*] IIRC someone once sent a patch against Automake to introduce
`?=' as "assign and allow future redefinitions".
