python2 contains a bundled copy of libffi which is currently out of sync with
the latest libffi release. There is an option to use a system libffi, buildroot
already uses it for the target python2 build and for python3. In python3, the
bundled copy doesn't exist anymore and the system-provided libffi is required.
The bundled copy currently fails to build on aarch64 host due to a missing
definition of AARCH64_CALL_CONTEXT_SIZE. This define was removed from the
headers in recent libffi releases and the host compiler might be including the
system headers before the bundled headers.
To solve this and since buildroot already relies on system libffi for target
python2 and python3 anyway, switch host python2 to use system libffi.

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 OFTC IRC.
