Warnings and errors building with clang #310
Description
While working on #307, I tried to compile on linux-xanmod (to get v6.15-7). I faced following issue:
$ make
. . .
warning: the compiler differs from the one used to build the kernel
The kernel was built by: Debian clang version 19.1.7 (3)
You are using: gcc (Debian 14.2.0-19) 14.2.0
CC [M] lua/lapi.o

So I tried:
