toolchain: fix detection of SSP support

Browse Source 
GCC issues a warning message if -fstack-protector is passed but SSP is
not available, so in order to force the compilation to fail we must also
pass -Werror.

All external toolchains were verified. The only one whose configuration
incorrectly selected BR2_TOOLCHAIN_HAS_SSP was CodeSourcery NIOSII.
