commit: https://git.buildroot.net/buildroot/commit/?id=0701c33e7a0cebcd76cc4e16d55f13ac516748a4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x
With Microblaze Gcc version < 8.x the build hangs due to gcc bug
85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. The bug
shows up when building prboom with optimization but not when building
with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y we
force using -O0.
