gcc-4.7.x, gcc-4.8.x and gcc-4.9.x don't propagate CXXFLAGS_FOR_TARGET to CXXFLAGS for libstdc++ build. As a result libstdc++ is built without TARGET_CFLAGS and may fail to link with applications using it, see e.g. http://autobuild.buildroot.net/results/81a3bca5cbcf789c7ce1aa221a6a4154dd7c3917/ Instead of passing TARGET_ABI or TARGET_CFLAGS for libstdc++ in --enable-cxx-flags parameter backport the patch that fixes propagation of CXXFLAGS_FOR_TARGET to CXXFLAGS. This issue is fixed in gcc-5.x Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Reviewed-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Reviewed-by: "Yann E.
