tiarmlnk generates cinit record for tiny .init_array section

Compiling and linking a simple C++ "Hello World" program such as the following:

#include <iostream>
using namespace std;

int main()

will cause the linker to generate an auto-initialization record for the compiler-generated .init_array section that is larger than the actual .init_array section.

If possible, the linker should avoid generating an auto-initialization record for the .init_array section when it is inefficient to do so.
