Log message:
On OpenBSD disable the malloc/calloc/realloc/free/str*dup builtins, since
they can perform strange transforms and optimizations. Some of those could
gain a slight advantage, but would avoid the variety of important runtime
checks our malloc(3) code does. In essence, the transforms performed are
considered "anti-mitigation".
