With Microblaze Gcc version < 8.x the build hangs due to gcc bug 85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. This package has been excluded from building on Microblaze due to this. To be consistent with how we deal with this issue in other packages, we re-enable the package and instead work around the issue by building with -O0, since gcc bug 85180 manifests itself only when optimization is enabled. To achieve this pass -O0 in CMAKE_CXX_FLAGS and remove 'depends on !BR2_microblaze' and its comment if not available from Config.in. Note that the comment was talking about gcc bug 68476, but this gcc bug is a duplicate of 85180. Since all Buildroot packages now use the reference to gcc bug 85180 and the option is named BR2_TOOLCHAIN_HAS_GCC_BUG_85180, we use this naming as well for bullet.
