SPARC is one of the CPUs which has a funny syscall ABI for the
pipe syscall; add it to the set of special cases in do_pipe().

bash is much more useful with this patch -- without it, it will
close() stdin instead of one end of its pipe to a child process,
so after the first time you run a program bash will exit...
It's this kind of "basic stuff doesn't work" that makes me
happier about being a bit cavalier with code cleanups,
enabling NPTL, etc for some of the minor target archs in
linux-user -- it's clear that some of them have simply never
been tested for anything more serious than "run some trivial
binary"...
