Add dkms.conf

[marcosfad]

dkms makes it much easier to build and maintain.

Tested with mbp 16,1 and kernel 5.6.11

@marcosfad @networkException 👋 Sorry to bother you, any idea on how to compile it with clang ?
OpenMandriva is switching to full clang for the next release, and I didn't succeed to make it work. ><

CC [M]  /usr/src/apple-bce-0.1/apple_bce.o
clang-15: error: unknown argument: '-mpreferred-stack-boundary=3'
clang-15: error: unknown argument: '-mindirect-branch-cs-prefix'
clang-15: warning: optimization flag '-falign-jumps=1' is not supported [-Wignored-optimization-argument]

Thank you very much in advance for your help

To reply to my own thread, actually it's working with the following config :

PACKAGE_NAME=apple-bce
PACKAGE_VERSION=0.1
CLEAN="make clean"
MAKE[0]="make CC=clang CXX=clang++ LD=ld.lld AR=llvm-ar NM=llvm-nm OBJCOPY=llvm-objcopy OBJSIZE=llvm-size STRIP=llvm-strip"
BUILT_MODULE_NAME[0]="apple-bce"
DEST_MODULE_LOCATION[0]="/updates"
AUTOINSTALL="yes"
REMAKE_INITRD="yes"

Build passed on the distro OpenMandriva Lx release 23.03 (ROME) Rolling for x86_64
With kernel 6.2.6-desktop-1omv2390 on a Macbook Air Intel mid 2020.
And OpenMandriva 15.0.7-3 clang version 15.0.7 as the toolchain
Architecture x86_64-pc-linux-gnu

Here is the logs:

• Trackpad (Not working for me)
• Audio

Using an external mouse so ok for now. If that can help someone.
