This seems to be gone in recent versions of QEMU. I found two new errors we can work around, and generated MCVEs reported for ppc32 (https://gitlab.com/qemu-project/qemu/-/issues/1779) and ppc64le (https://gitlab.com/qemu-project/qemu/-/issues/1780). See #357 reenabling ppc64le.

@calebzulawski what's a version of QEMU that's fixed? (don't need a bisection, just "use at least QEMU x.y.z")

The new version of cross seems to use 6.1.0 (which isn't particularly new)
