This will allow toolchain to indicate if they support -fstack-protector-strong or not. Whenever the gcc version is >= 4.9, we always have SSP_STRONG support if we have SSP support. However, some toolchains older than gcc 4.9 might have backported SSP_STRONG support, which is why we cannot rely just on BR2_TOOLCHAIN_GCC_AT_LEAST_4_9. Having this "default" value allows to avoid adding a "select BR2_TOOLCHAIN_HAS_SSP_STRONG" in the internal toolchain logic plus in almost external toolchains. But it allows custom external toolchains that are pre-4.9 to potentially declare that they support strong SSP.
