in pipe2, use pipe() rather than __syscall(SYS_pipe, ...) for fallback
SYS_pipe is not usable directly in general, since mips has a very broken calling convention for the pipe syscall. instead, just call the function, so that the mips-specific ugliness is isolated in mips/pipe.s and not copied elsewhere.
