Config file

Using Debian Squeeze (i386) with GCC 4.4.5, with uclibc 0.9.31.x and binutils 2.21 selected for a target i386 system, make -j3 dies at the configure step for binutils.

Here's the error:

It had successfully built a few packages already, but I wasn't logging those.
This appears to be a quite different problem from 1789, since it's at the configure stage.
