Compiles and works fine on Ubuntu 22.10.

#18 might have caused this

@txomon It still crashes using the latest d0f855a

Hello guys;

I am too trying to run chat under FreeBSD 13.1.
Chat compiles cleanly, but when launching it:

./chat
/antimatter15-alpaca.cpp-9116ae9]$ ./chat
main: seed = 1680984151
llama_model_load: loading model from 'ggml-alpaca-7b-q4.bin' - please wait ...
Illegal instruction (core dumped)
==
I tried "truss ./chat, and got:
===
[...]
ead(3,"\M-)t(I\M^R\M-~;\M-8\M^Ww\M^F{"...,32768) = 32768 (0x8000)

and finnaly, dbugging with gdb:

]$ gdb ./chat

My loader.conf has the following:

Helo would be appreciated.
