Because plugin in collect2 imply verbose output, we now output two lines that
match libtools egrep "\-L". One is collect2 command line, other is command line
calling collect-ld.  Consequently libtool adds every object twice that has
interesting ill effects.

I guess libtool should be updated to parse the output more safely, but still we
would break existing libtool setups that is bad enough. So I guess I will disable
this code implying verbose flag in collect2 on LTO?

Not my area, but I agree this looks like a remnant of debugging.
