Illegal Instruction while Trying to Run Cargo

[iamrecursion]

Installing cargo via apk and then attempting to run it crashes with an illegal instruction. The same issue occurs seemingly with any binary built in rust, including rustc itself.

Repro

> apk add cargo
> cargo

The dmesg output for the crash is below.

Hi! This seems to be the same as #805 (and #67)

[sferrini]

Just updated iSH to App Store v1.1.1 (Build 91) and got this new illegal instruction:

iPhone:~/data/yolo# cargo run
Illegal instruction
iPhone:~/data/yolo# dmesg
55 illegal instruction at 0x568067f6: 0f 11 42 24 8b 55 e8 66 
iPhone:~/data/yolo# rasm2 -b 32 -d "0f1142248b55e866"
movups xmmword [edx + 0x24], xmm0
mov edx, dword [ebp - 0x18]
invalid

[sferrini]

And rustc fails with:

iPhone:~/data/yolo/src# rustc main.rs 
Illegal instruction
iPhone:~/data/yolo/src# dmesg
33 stub syscall 375
34 illegal instruction at 0xf452a642: 0f 61 e8 66 0f 62 e8 66 
iPhone:~/data/yolo/src# rasm2 -b 32 -d "0f 61 e8 66 0f 62 e8 66"
punpcklwd mm5, mm0
punpckldq xmm5, xmm0
invalid
