If you say so :) I really am no autoconf wizard at all. If it's that

I guess I had originaly been thinking that maybe we'd want to test for
posix_fallocate, and whether we had a glibc version that wired it to the
fallocate syscall, etc etc... but really, going forward it's probably
sufficient to just check for fallocate itself, and not worry about the rest.
