expand the macro "DEFINE_STUB_FUNCTION" one by one !  Because I have no other
good idea.

You can open JITStubs.cpp with EditPlus, then replace
  DEFINE_STUB_FUNCTION\(([a-zA-Z_*]+), ([a-zA-Z_]+)\)\n
with
 extern "C" {
\1 JITStubThunked_\2(STUB_ARGS_DECLARATION); 
    }; 
__asm \1 JIT_STUB cti_\2(STUB_ARGS_DECLARATION)
{
    ARM
    str lr,[sp,#32]
    import JITStubThunked_\2
    bl JITStubThunked_\2
    ldr lr,[sp,#32]
    bx lr    
}
\1 JITStubThunked_\2(STUB_ARGS_DECLARATION)\n
