Binutils 2.24 produces broken code when compiling the kernel for ppc64le, so prevent this combination. See: https://sourceware.org/ml/binutils/2013-12/msg00200.html The problem manifests early in the boot process with "Kernel access of bad area, sig: 11" in arch_match_cpu_phys_id(). The fix has been merged upstream as commit 57fa7b8c7e59e35bced580f9bcb9668af43fdbce, which is available since Binutils 2.25.

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.
