log output of build for FreeBSD mips kernel and diagnostic/crash files from
clang.

clang will fail to parse the nonsense we are doing in exception.S during out
mips builds and eventually will crash.  I've attached the full build output and
the diagnostic files to this ticket.  There's a lot going on here.
