+Subject: [PATCH 17/39] libtool
+
+libstdc++ from gcc-runtime gets created with -rpath=/usr/lib/../lib for qemux86-64
+when running on am x86_64 build host.
+
+This patch stops this speading to libdir in the libstdc++.la file within libtool.
+Arguably, it shouldn't be passing this into libtool in the first place but
+for now this resolves the nastiest problems this causes.
+
+func_normal_abspath would resolve an empty path to `pwd` so we need
+to filter the zero case.
