commit: https://git.buildroot.net/buildroot/commit/?id=02d0c78da5869cb3b24935071cad86dcce777f8b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

In Buildroot, the SSP flags are passed via the wrapper, and only flags
supported by the toolchain will be used.

Add patch to remove '-fstack-protector-strong' compile flag.

Fixes:
  .../aarch64-buildroot-linux-uclibc/bin/ld: runlevel.o: in function `main':
  runlevel.c:(.text.startup+0x4): undefined reference to `__stack_chk_guard'
  .../aarch64-buildroot-linux-uclibc/bin/ld: cannot find -lssp_nonshared
  .../aarch64-buildroot-linux-uclibc/bin/ld: cannot find -lssp
