I'm wondering if there's a known problem with PPC linux-user. It
appears that static binaries work, but those that are dynamically linked
seem to always fail in the same way:
./ppc-linux-user/c2-qemu-ppc -L /var/chroots/ppc /var/chroots/ppc/bin/ls /

qemu: uncaught target signal 11 (Segmentation fault) - exiting
Segmentation fault
qemu.log shows that the last two tb appear to be identical - which is
odd that it fails (sorry for the spewage):
