Crash on an `endbr64` instruction.

[RnMss]

My build crashes inferencing with a model with "Illegal Instruction". I debugged it and seems to crash on an endbr64 instruction. I think my CPU doesn't support the instruction set. Is there a building option to turn off the instruction set?

Version: Master, commit e84c446d9533dabef2d8d60735d5924db63362ff

Command to reproduce python rwkv/chat_with_bot.py ../models/xxxxxxx.bin

It crashed with "Illegal Instruction"

I debugged the program:

> gdb python 
(gdb) handle SIGILL stop
(gdb) run rwkv/chat_with_bot.py ../models/xxxx.bin
