restorecon() has become nothing more than a small wrapper around selinux_android_restore(). This itself isn't super problematic, but it is an obstacle for compiling util.cpp on the host as that function is not available on the host. Bug: 36970783 Test: Boot bullhead Merged-In: I7e209ece6898f9a0d5eb9e5d5d8155c2f1ba9faf Change-Id: I7e209ece6898f9a0d5eb9e5d5d8155c2f1ba9faf
