        Implement Darwin PowerPC ABI.
        * configure.in: Handle powerpc-*-darwin*.  
        * Makefile.am: Set source files for POWERPC_DARWIN.
        * configure: Rebuilt.
        * Makefile.in: Rebuilt.
        * include/ffi.h.in: Define FFI_DARWIN and FFI_DEFAULT_ABI for
        POWERPC_DARWIN.
        * src/powerpc/darwin.S: New file.
        * src/powerpc/ffi_darwin.c: New file.
