cargo on ppc64 fails: invalid instruction: *EDIT*: on ntpdate as well
Description of problem:
Machine boots,
but when compiling a rust library, the following issue appears:
```
cargo build --release --manifest-path rust-src/Cargo.toml
cargo[376]: illegal instruction (4) at 12e0933c0 nip 12e0933c0 lr 12dd7c768 code 1 in cargo[12dc10000+956000]

make: *** [Makefile:129: libbcachefs.a] Illegal instruction (core dumped)
make: *** Deleting file 'libbcachefs.a'
```
the core dump files of cargo and ar are attached
~~I have no clue whether this is a rustc or qemu bug, so please let me know if this issue should be forwarded to rust devs~~
EDIT: as this happens with ntpdate as well, I think it's an emulator issue:
```
ntpdig[1179]: illegal instruction (4) at 102382c4 nip 102382c4 lr 102382a8 code 1 in python3.11[10000000+63e000]

```
Steps to reproduce:
1. create a debian ppc64 root image using debian sid & debootstrap
2. install rust using rustup
3. compile bcachefs-tools in ppc64
2b. Install ntpdate using apt-get ntpdate
3b. run ntpdate
Additional information:
Core dump command:
```
cat /proc/sys/kernel/core_pattern
|/bin/cp --sparse=always /dev/stdin /host//repos/janpieter/linux/bcachefs/ktest-out/core.%e.PID%p.SIG%s.TIME%t
```
