Subject: [bug#69990] [PATCH] gnu: llama-cpp: mark as tunable per CPU architecture

From: John Fremlin <[email-masked]>
Date: Sun, 24 Mar 2024 17:05:49 -0400

* gnu/packages/machine-learning.scm (llama-cpp): add tunable property.

Otherwise llama-cpp will use FMA4 instructions leading to SIGILL on even
recent AMD chips, that do not support them.
