Ok. I finally figured it out.

lang/gcc{48,49,5} lacks -fformat-extensions support, but devel/powerpc64-gcc has it. I will revert the commit to base and request an MFC to ^/stable/11. The support for -fformat-extensions needs to be added to lang/gcc* for consistency — I will file a ports bug for that.

Thanks,
