branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The lua-cqueues package exhibits gcc bug 68485 when built for the
Microblaze architecture with optimization enabled, which causes a
build failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_68485=y.
Fixes:
