With Microblaze Gcc version < 8.x build gives: 'Error: operation combines symbols in different segments' This is due to bug 63261: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261. To avoid this, the fxload package has a !BR2_microblaze dependency. However, gcc bug 63261 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_63261, and re-enables fxload on Microblaze.
