I have to ask: how did you figure out which file was the source
of the problem? I was using strace to figure out which one was
the problematic command, but that was as far as I had gotten.

No, because:
files := $(foreach p, $(foo), $(foo2.$(p)) )
is iterating over $(foo) and expanding $(p) in the second
expression, producing:
$(foo2.a)
$(foo2.b)
$(foo2.c)
$(foo2.d)
which in turn gets expanded again. As the variables foo2.a,
foo2.b, etc, don't exist, files is blank.
To get what you expect, you'd have to write:
files := $(foreach p, $(foo), $(foo2).$(p) )
I suspect this is not the issue in localize.mk.
