Ease of maintenance, mainly. Having it in a separate file makes it easier to 
migrate the code to new GCC releases. Also, collect2.c is already 2658 lines, 
which is more than I typically like to have in a single source file.

I'd like to turn the question around: is there an advantage to merging them?

In any case, if I can make it work as a separate process, it shouldn't be hard 
to merge it into collect2 later.
