package/kismet: work around gcc bug 85180
With Microblaze Gcc version < 8.x the build hangs due to bug 85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. The bug shows up when building kismet with optimization but not when building with -O0. To work around this, if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y we force using -O0.
