Proposed patch

Here is a possible implementation of the feature.  Please let me know what you
think.

One thing that stands out to me as maybe being an issue is the fact that the
new option is position dependent - it only affects filenames that come after it
on the command line.  (Much like the -L option).  So:

  ld foo.o --remap-inputs=foo.o=bar.o

will not rename foo.o to bar.o, whereas:

  ld --remap-inputs=foo.o=bar.o foo.o

will perform the renaming.

One other thing: I wondered if we ought to accept the "@file" syntax in the
--remap-inputs option, as a synonym for --remap-inputs-file.  What do you think
?
