            Bug ID: 65537
           Summary: [5 Regression]: --with-build-config=bootstrap-lto
                    fails on CentOS 5.11
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal

When configured with --with-build-config=bootstrap-lto, the bootstrap fails on
CentOS 5.11 in libiberty with:

The problem is with gcc-ar that unconditionally passes --plugin option to ar. 
This fails on older binutils, such as:

$ ar --version
GNU ar 2.17.50.0.6-26.el5 20061020

LTO bootstrap worked a while ago, so this is a regression on 5.0 branch.
