From d7c34c8f60051d16ea02a66b43460115eca408d4 Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Thu, 1 Jun 2023 10:21:21 -0400 Subject: [PATCH] selinux: don't use make's grouped targets feature yet commit 42c4e97e06a839b07d834f640a10911ad84ec8b3 upstream. The Linux Kernel currently only requires make v3.82 while the grouped target functionality requires make v4.3. Removed the grouped target introduced in 4ce1f694eb5d ("selinux: ensure av_permissions.h is built when needed") as well as the multiple header file targets in the make rule. This effectively reverts the problem commit. We will revisit this change when make >= 4.3 is required by the rest of the kernel.
