With Microblaze gcc version <= 9.x, the build of flannel fails due to gcc bug 68485: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68485. To avoid this, the flann package has a !BR2_microblaze dependency. However, gcc bug 68485 only triggers when optimization is enabled, so we can work around the issue by passing -O0, which is what we do in other Buildroot packages to work around this bug. So, this commit passes -O0 when BR2_TOOLCHAIN_HAS_GCC_BUG_68485, and re-enables flann on Microblaze. Note that the comment was talking about gcc bug 69401, but this gcc bug is a duplicate of 68485. Since all Buildroot packages now use the reference to gcc bug 68485 and the option is named BR2_TOOLCHAIN_HAS_GCC_BUG_68485, we use this naming as well for flann.
