commit: https://git.buildroot.net/buildroot/commit/?id=d710bd6085d4bb89d97093c7e89585c90181a94e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.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
