Did you by any chance evalue the use of INPUT in linker files.
Stephen back then (again based on proposal from Alan Modra),
also made an implementation using INPUT.

The problem with that idea was that (at least for some versions of
binutils in use at the time) we hit a static limit to the number of
object files and ld just stopped at that point. :-(

I played with a nearly identical patch to work around the inability to 
do LTO and 'ld -r' with mainline binutils.  However this also requires 
major changes to modpost otherwise it becomes ineffective.
