Log Message:
-----------
Trap SIGBUS when Configure checks for va_copy (#18148)
On several systems the attempt to determine if we "need va_copy() or
similar" results in a SIGBUS instead of a SIGSEGV because the fault
happens pointing at an io device address.
While reviewing accounting logs during the OpenBSD system build, bluhm@
noticed a core dump and deraadt@ tracked it down.
While researching it was discovered that this is a fairly common case in
other systems as well.
