This allows building libucontext against newlib.

ppc32/64: correct signature of function parameter to makecontext
...
Because makecontext can pass a set of integer arguments to the provided
function, it is incorrect to require that this function accept no
parameters.

ppc32/64: simplify storage of stack parameters
...
The switch statement is simpler as an if/else, and removing the argp
variable makes the code more symmetric between the register and stack
parameter cases.

ppc32/64: don't store uc_link on the stack
...
This was previously stored either in the CR (ppc64) or LR (ppc32) save
area of the stack, or to one of the parameter save slots.
In either case, the saved value was unused. This value is also passed
to __start_context via r31, so there's no need to pass it on the stack.

ppc32/64: fix back chain pointer
...
The ABI states that sp[0] should point to the previous stack frame, or be
zero if there is no previous stack frame. makecontext previously set this
slot to point to the __start_context function, rather than to a valid
stack frame.
