package/chocolate-doom: work around gcc bug 85180

Browse Source 
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 chocolate-doom with optimization but not when building
with -O0. To work around this bug, if
BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y, we force using -O0.

Fixes:
