I am trying to build Linux From Scratch, and now I am at chapter 5.4, which tells me how to build Binutils. I have binutils 2.20's source code, but when I try to build it:

time { ./binutils-2.20/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-werror ; }

it gives me an error:

checking build system type... i686-pc-linux-gnu

See `config.log' for more details.

You can see my config.log at pastebin.com: http://pastebin.com/hX7v5KLn

I have just installed Ubuntu 10.04, and reinstalled GCC and installed G++. Also, the build is done by a non-root, non-admin user called 'lfs' (which is also described in Linux From Scratch), and on a different partition than where the system is installed.

Can anyone help me? Thanks
