[PATCH] [GOLD] Add plugin API for processing plugin-added input files

[Stephen Crane]

Thank you so much. I just added documentation for the new hook to
https://gcc.gnu.org/wiki/whopr/driver so that should finish off this
feature.

I'm happy to fix any bugs that might crop up related to this hook, of
course. I don't follow the binutils list closely, so I apologize in
advance if I miss any issues related to this feature. Just CC me
explicitly and I'll jump on it.

Thanks,
- stephen
