[Buildroot] [PATCH 2/3] toolchain/toolchain-external/toolchain-external-custom: add option to indicate SSP_STRONG support

[Yann E. MORIN]

Thomas, All,

On 2020-02-20 03:01 +0100, Thomas Petazzoni spake thusly:
> 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.
