But they don't use objcopy, they use strip.  The goal is to switch  
i386-pc from the buggy and simple objcopy to more powerful and  
flexible ld.  The same could be done to replace strip for other  
platforms while keeping ELF format for the output.

I agree that we should avoid naming highly target-specific linker  
scripts in a generic way.  "i386-pc.ld" might be a better name.  The  
linker script for modules perhaps could be generic, but this is for  
*.img files.
