In our 8.0 based systems at $JOB our build environment made heavy use of the

We are trying to move up to a newer release but suddenly the --sysroot option 
has disappeared.

we get the message "/usr/bin/ld: this linker was not configured to use sysroots"
more spefically the following command (from 'configure') fails on "near 9"
and succeeds on 8.0.

Does anyone know what happened?  and when, and by who?
I have looked in the Makefiles and configuration files in SVN and I can't see a 
change that would have done this..
of course the building of these tools is rather complex so I may have missed 
some place..
Yea, I looked too and don?t see anything. I thought it was broken in more like 
2005 not 2011. You?re only hope is to bisect the tree down to the change that 
caused it?
It's been broken since at least the last binutils import and probably
longer since the inane ld behavior of activating --sysroot only when
built with a specified sysroot is from upstream.  The fix is trivial, just
merge r257268 and r257530 to the branch you are using.

yeah I did that yesterday..  worked like a charm.
