It's part of the build process for ld itself -- it has the ability to 
parameterize standard linker scripts to deal with a small number of 
common target differences.

The standard elf script is ld/scripttempl/elf.sc and it has a number of 
parameters that can be set to build scripts which are customized for the 
target.  And example of customization is ld/emulpararms/mn10300.sh.

When building the linker from source it will build a set of standard 
linker scripts using the template and parameter files suitable for the 
target system.

Now having said that, I don't think it's likely to resolve any of the 
issues you're raising as they require defining new output memory regions 
and more importantly what input sections should be placed in those 
regions.    Typically what I would recommend would be to take the 
standard linker script for your target and add the output sections 
specific for your part to that linker script.
