Add a patch to filter -Wl,--no-undefined as -Wl,-z,undefs was only
added in binutils 2.30, and therefore is not available in some older
toolchains, causing build failures such as:
/home/naourr/work/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/aarch64_be-linux-gnu/7.3.1/../../../../aarch64_be-linux-gnu/bin/ld: warning: -z undefs ignored.
