* SELinux and Seccomp are now enabled via the kernel options themselves
* Config.in now uses CGroupsV2 by default but optionally allows V1

-Subject: [PATCH] imporve hardcoded CC on cross compile
-
-Since commit applied in moby [61a3285 Support cross-compile for arm]
-it hardcoded var-CC to support cross-compile for arm
-
-Correct it with "${parameter:-word}" format, it is helpful for user
-define toolchains
-
-(Use Default Values.  If parameter is unset or null, the expansion of
-word is substituted.  Otherwise, the value of parameter is substituted.)
