The switch to private LIBGCC causes 'undefined instruction' exception in at least the Open-RD Ultimate and Client, and quite probably the Open-RD Base as well.
While debugging this issue, it appeared the switch to architecture-optimized memset and memcpy also causes the same exceptions. Until a fix to private libgcc and architecture-optimized memcpy and memset is mainlined, disable their use in all openrd configurations.
