Subject: [PATCH] nss: add nss-tools

Network Security Services (NSS) is a set of libraries designed
to support cross-platform development of security-enabled client
and server applications. Applications built with NSS can support
SSL v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME,
X.509 v3 certificates, and other security standards.

+Description:             Adds auto-generated nss.pc and nss-config script, and
+                         allows building without nspr in the source tree.
+                         For 3.40.1, Requires: updated to nspr >= 4.20.
