Ah, I can explain it, collect2 does `stuff', and what it does is to remove the
lto temporary files, early. The below are the files that are too early, and
will `fix' the issue.
Index: collect2.c

If collect2 was folded into gcc.c and all the lto stuff was flat, inside gcc.c
and then we let record_temp_file register _all_ the temporary files, and the
let gcc.c delete the temporary files at the end, all work work just fine.
