For the hosted implementation, we just need to pass the appropriate options at compile and link time. No further arch-specific code needed. Because we define our own handlers in lib/ubsan.c, linking against libubsan isn't strictly required. We do it anyway on sandbox, so we can use the backtrace functionality within.
