    The answer to both questions is Yes.

Let me explain the relevant steps in order.

- The pre-link step is an independent tool invocation. Here, an input file containing app specific information is processed to generate a linker script for the linker.

- The next step is the link step, which is another tool invocation. This uses the file generated in the prelink step as one of the inputs. Since the file is a linker script, it should be passed to the linker with a "-T" flag

    The <linker_script_name.ld> file would have a pre-defined name, which gets decided similar to 'C' files.

eg. %.ld: %.ldi    [ multiapp.ld: multiapp.ldi ]

So the name and location of the linker script cannot be specified/changed by the linker.

Note that not all projects would have an app-specific linker script to be generated, so the "-T" option should get added to the command line only for a project having a linker script generated.
