Details:

When I upgraded to clang-6.0.0 on Linux, a build of my code triggered a
warning:

 Compiling file derived_src/NSFramework_AkamaiKit.m ...
derived_src/NSFramework_AkamaiKit.m:2:12: warning: class
'NSFramework_AkamaiKit' defined without specifying a base class
[-Wobjc-root-class]
@interface NSFramework_AkamaiKit
           ^
derived_src/NSFramework_AkamaiKit.m:2:33: note: add a super class to fix this
problem
@interface NSFramework_AkamaiKit
                                ^
                                 : NSObject 

I can work around this by adding -Wno-objc-root-class to my build, but it
would be better if this auto-generated code could could be wrapped in a macro
that would prevent the warning.  It's correct for there to be no super class.
