+Add missing MSG_CMSG_CLOEXEC
+
+Unpatched uClibc toolchains, even using the latest 0.9.33.2, do not
+have the MSG_CMSG_CLOEXEC definition. Even though the Buildroot
+internal toolchain backend has a uClibc patch to provide it, it
+doesn't apply to external toolchains. This patch provides the
+definition of MSG_CMSG_CLOEXEC.
