allow archs to provide a 7-argument syscall if needed

commit 788d5e24ca19c6291cebd8d1ad5b5ed6abf42665 noted that we could
add this if needed, and in fact it is needed, but not for one of the
archs documented as having a 7th syscall arg register. rather, it's
needed for mips (o32), where all but the first 4 arguments are passed
on the stack, and the stack can accommodate a 7th.
