Commit Message

Giulio Benetti Feb. 5, 2024, 5:23 p.m. UTC 
The htop package exhibits gcc bug 109809 when built for the RISCV64
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_109809=y.

Fixes:
still not happened. It shows up while building under docker-run this
pending patch-set:
