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. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
