If the kernel is built with gcc 9.2, those compiler flags are enabled:
CONFIG_CC_HAVE_STACKPROTECTOR_SYSREG=yCONFIG_STACKPROTECTOR_PER_TASK=y
But since Debian Buster ships with 8.3., we can't build modules on board. More info: https://github.com/armbian/build/issues/2245
Since we urgently don't need to stick to 9.2, compiling kernel with 8.3 seems like a viable workaround.
