util/oslib-posix: Forward SIGBUS to MCE handler under Linux
Temporarily modifying the SIGBUS handler is really nasty, as we might be unlucky and receive an MCE SIGBUS while having our handler registered. Unfortunately, there is no way around messing with SIGBUS when MADV_POPULATE_WRITE is not applicable or not around. Let's forward SIGBUS that don't belong to us to the already registered handler and document the situation. Reviewed-by: Daniel P.
