I'm not sure what you mean.  Each object file will have a .init_array section. 
The linker will assemble those sections in the usual manner.

The order of global constructors in a single translation unit is fixed by the
language standard.  The thing that is not fixed is the order between
translation units.  So each object file will have a .init_array section that
will typically contain only a single pointer.  The order in which those input
.init_array sections are combined into an output .init_array section will
determine the order in which the constructors are run.
