Building dmalloc on Microblaze with optimization enabled and gcc < 8.x fails with: Error: operation combines symbols in different segments This is due to gcc bug 63261 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261). To avoid this, the dmalloc 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 dmalloc on Microblaze.
