[PATCH] use one send_to_ppe function for both spu libc and libgloss

Hi Patrick,
Sorry. This patch ended up in my Trash folder - not sure why it got
there (perhaps I was a little quick in my deleting of something else).
Anyway, regarding the header file: sys/send_to_ppe.h. Did you intend
to expose this to the end-user? If not, then it should just be a
local.h file in the machine/spu directory that all the files can access
and you can resubmit. Otherwise, you might consider putting in a
sys/syscall.h header file. Let me know.
