Problems with libffi on PowerPC64

[Daniela Quaresima <daniela_quaresima at yahoo dot it>]

Hi! I'm having difficulties in using JNA on IBM (x series) ppc64 architecture with Linux SUSE SLES 9.
It was suggested that maybe the problem was in the libffi used.
I tried to run libffi testsuite as follows:
-starting in the lidffi directory inside jna/native
mkdir build; cd build; ../configure; make; make check

Some tests failed and so I wanted to know how I could resolve my problem and (hopefully) make JNA work.
I also tried to install libffi (version 3.0.8) as a standalone, but the testsuite failed even in that case.

This is the result of the tests for the jna/native/libffi:

Native configuration is powerpc64-unknown-linux-gnu

                === libffi tests ===

Can someone tell me what could be the problem and what steps should I take to resolve it?
