s3-gse Work around the MIT 1.9 gss_krb5_import_cred
We detect this function at configure time, but it currently fails to
operate the way we need - that is, when the principal is not
specified, it gives this error. When the principal is specified we
get 'wrong principal in request' in the GSS acceptor, so for now the
best option is to fall back to the alternate approach.
