The trinity configure script looks into a host header to check for libc/kernel
headers conflict resolution. This is not compatible with cross compilation.
Add a patch that does direct compilation test instead.
This issue was not caught by the autobuilder yet.

+Subject: [PATCH] configure: fix cross compile detection of broken ipv6 headers
+
+Checking the content of the host ipv6.h headers is incompatible with cross
+compilation. Target headers may not be the same as the host. Do direct build
+test instead using the ${CC} (cross) compiler to detect headers issues.
+
+Define _GNU_SOURCE to make sure glibc ipv6 definitions are exposed.
