Guess not - just before reporting the bug I upgraded to the latest
experimental version, so there should've been a reinstall just before.

I worked around that for now via
# cat debian-jessie-ppc64el/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1
#!/bin/bash
shift
/usr/bin/qemu-ppc64le-static
/usr/lib/gcc/powerpc64le-linux-gnu/4.9/cc1.debian-bug "$@"
