libnftnl: add patch to fix libnftnl.pc for static linking
This commit adds a patch to libnftnl to add the Libs.private field in the pkg-config file, which is needed for proper static linking of applications using libnftnl. Fixes the build of programs such as nftables on Blackfin: http://autobuild.buildroot.org/results/061/06166344cc8e162d3f901c70ee31ce07e481053e/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

+Subject: [PATCH 2/2] Add Libs.private field to libnftnl.pc
+Static linking userspace programs such as nftables against libnftnl
+currently doesn't work out of the box, because libnftnl is linked
+against libmnl, but this isn't expressed in libnftnl pkg-config
+ CCLD nft
+[...]/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libnftnl.a(table.o): In function `_nft_table_nlmsg_parse':
+table.c:(.text+0x480): undefined reference to `_mnl_attr_parse'
+table.c:(.text+0x492): undefined reference to `_mnl_attr_get_str'
+table.c:(.text+0x4a8): undefined reference to `_mnl_attr_get_u32'
+table.c:(.text+0x4ca): undefined reference to `_mnl_attr_get_u32'
+The Libs.private field is specifically designed for such usage:
+From pkg-config documentation:
+ Libs.private:
+ This line should list any private libraries in use. Private
+ libraries are libraries which are not exposed through your
+ library, but are needed in the case of static linking.
+Therefore, this patch adds a reference to libmnl in the Libs.private
+field of libnftnl pkg-config file.
