Missing whitespace between the calls to build2 and it's argument list.

Of course, if you used fold_build1 and fold_build2 instead of just
build1 and build2 respectively, the middle-end might be able to perform
these kinds of transformations for you :-)  For example, if len == 0,
this test would simplify to "a != b".
