For once, I totally agree. "Please leave that option away, that's the
default behavior" may fine, but it's fragile if you:

- want to ensure a certain feature is supported (and want the build to
  bail out if not)
- want to ensure a certain feature is not included.

The behavior of configure can change, so can the build environment, but
these requirements may be the same, so explicitly stating them is
totally valid, IMHO. (That said, there is a lot of configure overkill
out there.)
