imporve hardcoded CC on cross compile

Browse source 
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.)
