This commit adds a user-visible option BR2_TOOLCHAIN_EXTERNAL_HAS_SSP_STRONG, which will allow the user to indicate if the custom external toolchain does or does not have SSP_STRONG support. Depending on this, the user will be able to use (or not) the BR2_SSP_STRONG option. Checking if what the user said is true or not about this is already done in toolchain/toolchain-external/pkg-toolchain-external.mk: $$(Q)$$(call check_toolchain_ssp,$$(TOOLCHAIN_EXTERNAL_CC),$(BR2_SSP_OPTION)) If the user selects BR2_SSP_STRONG, this will check if -fstack-protector-strong is really supported.
