Ulrich Weigand 4f45d04c6f [ppc64] Patch in TOC restore code after all external function calls
When resolving a function call to an external routine, the dynamic
loader must patch the "nop" after the branch instruction to a load
that restores the TOC register.

Current code does that, but only with the *first* instance of a call
to any particular external routine, i.e. at the point where it also
allocates the call stub.  With subsequent calls to the same routine,
current code neglects to patch in the TOC restore code.  This is a
bug, and leads to corrupt TOC pointers in those cases.

Fixed by patching in restore code every time.
