I did not know about libffi ... I'll have to look if I should not replace
dyncall by libffi then. Thanks for the info.

I guess it is a bit of both. Given that libffi is supported on Linux/PPC64, I
guess having it on Linux/PPC should not be that much of a problem -- but still,
I think the calling convention can be slightly different between the two
architectures.
