+Subject: [PATCH] add BUILD_WITH_STACK_PROTECTOR option
+
+Add BUILD_WITH_STACK_PROTECTOR to avoid the following build failure with
+toolchains that don't support stack-protector:
+
+/home/buildroot/autobuild/instance-3/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mipsel-buildroot-linux-uclibc/9.3.0/../../../../mipsel-buildroot-linux-uclibc/bin/ld: utils.cpp:(.text._ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE12_M_constructIPcEEvT_S7_St20forward_iterator_tag[_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE12_M_constructIPcEEvT_S7_St20forward_iterator_tag]+0xd0): undefined reference to `__stack_chk_fail'
+
+Indeed, support for -fstack-protector-strong can't be detected through
+check_cxx_compiler_flag as some toolchains need to link with -lssp to
+enable SSP support
+
+Fixes:
