0004930: Patch for 0004841 doesn't solve the problem on PowerPC processors

Description

While trying to build Unison on Mac OS X, PowerPC:

    /Developer/usr/bin/gcc-4.0 -arch ppc -L/sw/src/fink.build/unison-aqua-2.27.57-1008/unison-2.13.16/uimac/build/Default -F/sw/src/fink.build/unison-aqua-2.27.57-1008/unison-2.13.16/uimac/build/Default -filelist /sw/src/fink.build/unison-aqua-2.27.57-1008/unison-2.13.16/uimac/build/uimac.build/Default/uimac.build/Objects-normal/ppc/Unison.LinkFileList -mmacosx-version-min=10.5 /sw/src/fink.build/unison-aqua-2.27.57-1008/unison-2.13.16/uimac/../unison-blob.o -L/sw/lib/ocaml -lunix -lstr -lasmrun -framework Cocoa -framework Security -o /sw/src/fink.build/unison-aqua-2.27.57-1008/unison-2.13.16/uimac/build/Default/Unison.app/Contents/MacOS/Unison

Additional Information

The fix in the 3.11 bugfix branch for i386 and amd64 does not apply to powerpc.

From asmcomp/i386/emit.mlp:

  if macosx
  && not !Clflags.output_c_object
  && is_generic_function fundecl.fun_name
  then (* PR#4690 *)
    ` .private_extern {emit_symbol fundecl.fun_name}\n`
  else
    ` .globl {emit_symbol fundecl.fun_name}\n`;

whilst in asmcomp/power/emit.mlp:

  if Config.system = "rhapsody" && is_generic_function fundecl.fun_name
  then (* PR#4690 *)
    ` .private_extern {emit_symbol fundecl.fun_name}\n`
  else
  ` .globl {emit_symbol fundecl.fun_name}\n`;
