I only figured out how to do CI testing for 32-bit PowerPC after the 3.3 release, and there are indeed a number of failures: https://github.com/libffi/rlgl-policy/blob/master/XFAIL#L202-L290 travis-ci testing is done with a powerpc-eabisim GNU toolchain. We need to start going through these failures assuming that powerpc-eabisim is a close approximation of the system you are using.
