Subject: [PATCH] guile: Cross build fix.

To cross-build, both the host guile and the native guile-for-build
must be available.  If the native guile is not available, no snarfing
is done and the guile cross build is skipped.

During the cross-build gnutls.scm does not load when compliling
extra.scm, becase of missing definitions from guile-gnutls-v-2.

* guile/modules/gnutls.in (protocol/ssl-3 protocol/tls-1.0,
protocol/tls-1.1, credentials/anonymous, cipher/rijndael-256-cbc,
cipher/rijndael-128-cbc, cipher/rijndael-cbc, cipher/arcfour-128,
certificate-verify/allow-any-x509-v1-ca-certificate,
certificate-verify/allow-x509-v1-ca-certificate): Define to #f
initially.  When "GNUTLS_GUILE_CROSS_COMPILING" not set, set! to value
from "guile-gnutls-v-2" load-extension C module.
