In commit2a27294e9a("grub2: force -fno-stack-protector in CFLAGS"), a fix was made to the grub2 package to make it build properly even when SSP support is enabled. However, commit20a4583ebf("security hardening: add RELFO, FORTIFY options") reworked how SSP options are passed, and they are now passed in CPPFLAGS instead of CFLAGS, making the fix introduced by2a27294e9ano longer operating. This commit will force no-stack-protector in CPPFLAGS instead of CFLAGS. Fixes bug #10961.

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.
