I'm not sure how what you are saying disagrees with what I am saying.
Your linker was not configured with --with-sysroot. The error message
above suggests strongly that the compiler is passing --sysroot to the
linker.

Now that you mention it, why are you using such an old version of the
binutils?
I've sometimes heard reasons for using old gcc releases, but I don't
know of any reasons to use old binutils releases. Old gcc releases
should work with new binutils.
