[Buildroot] [PATCH] package/bullet: re-enable package when gcc bug 85180 is present

With Microblaze Gcc version < 8.x the build hangs to gcc bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. This package has
been excluded from building if the toolchain is affected by gcc bug
85180. 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 to CMAKE_CXX_FLAGS in CONF_OPT and remove
'depends on !BR2_microblaze' and its comment if not available from
Config.in.
