Latest musl release supports ppc64 architecture (both big endian and little endian), so this commit adds support for this. Since musl implements the ELFv2 ABI for both big-endian and little-endian PowerPC64, we have to force using this ABI on PowerPC64 big endian (normally elfv1 is the default). Also, only gcc 6.x has the necessary changes to support musl on PowerPC 64, so we restrict the gcc version selection accordingly. Tested with Qemu for big endian and little endian configurations.

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.
