Hmm, while that's not surprising, I've used that combination of options (power8
big-endian with gcc 4.9.x and gcc 5.x) and it works fine for me. Have you tried
building from completely clean, including clearing or disabling ccache?

Maybe the host architecture matters? Is that x86_64? What gcc do you have on
the host?

Cheers,
Sam.
