Aha! The error is in crtbeginS.o. This is important: it is not one
of the files you compiled. Therefore, no matter what you do with
-mlongcall", it won't help. It may be that recompiling crtbeginS.o with
-mlongcall" would help, but we'd need a PPC export to confirm that.
It may be easier simply to split the shared library.
