configure: Fix check for fdatasync()
Under Darwin, a symbol exists for the fdatasync() function, so that our
link test succeeds. However _POSIX_SYNCHRONIZED_IO is set to '-1'.
According to POSIX:2008, a value of -1 means the feature is not supported.
A value of 0 means supported at compilation time, and a value greater 0
means supported at both compilation and run time.
Enable fdatasync() only if _POSIX_SYNCHRONIZED_IO is '>0'.
