+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]
+cargo[376]: code: 00000000 00000000 00000000 7c0802a6 f8010010 f821ff11 fba100d8 60000000

+make: *** [Makefile:133: rust-src/target/release/libbcachefs_rust.a] Illegal instruction (core dumped)
+make: *** Waiting for unfinished jobs....
+ar[375]: illegal instruction (4) at 3fff9b2a4dac nip 3fff9b2a4dac lr 3fff9b2a4da4 code 1 in libLLVM-16.so.1[3fff99f10000+792f000]
+ar[375]: code: f87d0028 7fa3eb78 b29d0090 f89d0020 4810a8c1 60000000 7f83e378 7fa4eb78

+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]
+ntpdig[1179]: code: 3d22ffdd c8094448 fc1e0000 41c2022c 4bde9b5d e8410028 3d42ffdd 39200000

+```
+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
