toolchain: set the ssp gcc option in kconfig
Currently, we repeat all the SSP level selection deep down to the toolchain wrapper itself, where we eventually translate it to the actual SSP option to use. This is a bit redundant. Additionally, we will want to check that the toolchain actually supports that option (for those toolchain where it was backported). So, move the translation into kconfig, and add the qstrip'ed value to the additional flags passed to the wrapper. Add it before user-supplied opitons, to keep the previous behaviour (and allow anyone crazy-enough to override it with BR2_TARGET_OPTIMIZATION). Signed-off-by: "Yann E.
