Apart from the HTML mail, you did well. ;-)

Yes, this is a known issue, albeit undocumented. :-/

This is due to patches/glibc/2.9/600-recent-binutils.patch which adds
support for binutils-2.20. At the time the patch was devised, 2.20.1
was not out yet.

Maybe, and I say _maybe_, you would get better luck trying glibc-2.10 or
2.11. Those two versions are still marked 'experimental' in crosstool-NG
(because there has been little test), so you'll have to enable them with:

    [*] Try features marked as EXPERIMENTAL

Definitely.

Update the path 600 to also add 2.20.1 as a special case, remove the
sources for glibc, and run again.
