So in this case we mostly need to include an internal header 
(epiphany-syscalls.h).  In a few cases an explicit prototype is added. 
We've also got a return with no value in a function with a non-void 
return type.  Finally the asm_syscall interface expects a pointer as its 
first argument.  In a few cases we've actually got an int (file 
descriptor) which we just cast to a void *.

It's slightly more than Jeff J's pre-approval, but I think still reasonable.

Pushed to the trunk.
