I think this cause the issue:

> '__clear_cache' was not declared in this scope
> make[1]: *** [obj/release/JSBase.o] Error 1

This is a gcc builtin function. Please check if its interface is declared.

see the "static void cacheFlush(void* code, size_t size)" in
JavaScriptCore/jit/ExecutableAllocator.h

This function calls a kernel utility to flush data cache memory (unfortunately
the required mrc instruction is only executable in kernel level).

There is a native NAPI implementation in the code if __clear_cache is not
declared in your gcc. If you have other solution for flushing the data cache,
just call that function.
