configure: Assimilate new getlinetest into recent configure conventions.

We're now using printf to print what we're checking before we check. We're
also making variables such as HAVE_GETLINE available to both make and to
the C pre-processor.

With this, the local getline implementation is now only compiled if not
available on the system.
