Subject: [PATCH] selinux: fix Makefile dependencies of flask.h
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: bcab1adeaad4b39a1e04cb98979a367d08253f03

[ Upstream commit bcab1adeaad4b39a1e04cb98979a367d08253f03 ]

Make the flask.h target depend on the genheaders binary instead of
classmap.h to ensure that it is rebuilt if any of the dependencies of
genheaders are changed.

Notably this fixes flask.h not being rebuilt when
initial_sid_to_string.h is modified.

Fixes: 8753f6bec352 ("selinux: generate flask headers during kernel build")
