buildroot: Bump to pick up GCC 8 ppc64le fix
When building on a ppc64le host we see this error:
build/genmatch --gimple ../../gcc/match.pd \
> tmp-gimple-match.c
../../gcc/match.pd:120:1 error: expected (, got NAME
negative value by 0 gives -0, not +0. */
This was reported upstream[1] and fixed on the GCC 6 [2] and GCC 7 [3]
branches:
Backport from mainline
2018-01-10 Kelvin Nilsen <kelvin@gcc.gnu.org>
* lex.c (search_line_fast): Remove illegal coercion of an
unaligned pointer value to vector pointer type and replace with
use of __builtin_vec_vsx_ld () built-in function, which operates
on unaligned pointer values.
The patches included in Buildroot contain just the code changes, and not
the changelog, to make it easer to manage backporting.
Tested on Ubuntu Cosmic ppc64le.

The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.
https://open-power.github.io/op-build/
See the doc/ directory for documentation source. Contributions are VERY welcome!
Issues, Milestones, pull requests and code hosting is on GitHub: https://github.com/open-power/op-build
See CONTRIBUTING.md for howto contribute code.
To build an image for a Palmetto system:
git clone --recursive git@github.com:open-power/op-build.git cd op-build . op-build-env op-build palmetto_defconfig && op-build
There are also default configurations for other platforms in openpower/configs/. Current POWER8 platforms include Habanero, Firestone, and Garrison. Current POWER9 platforms include Witherspoon, Boston (p9dsu), Romulus, and Zaius.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
