I don't have a solution for that problem.  Can you create a
minimal test case for this?  i.e.
 take command that failed from log, and turn it into a shell script
 that does
   #!/bin/sh
   PATH=...the path from the log...
   export PATH
   cd ...the directory from the log...
   [the command that failed]
Run that script, verify it fails in same way
Then add -E to the gcc command, remove -o ld-collate.o, and
save result in ld-collate.i
Compile ld-collate.i and verify same error
Repeat:
  Back up ld-collate.i
  Delete lines from ld-collate.i
  Verify error still happens on smaller file
until ld-collate.i is as small as possible

Compile minimal ld-collate.i with -save-temps
Post both ld-collate.i and ld-collate.s

Thanks!
