[Buildroot] Cannot compile gcc in target

[Barry Kauler]

Hi, I am new to Buildroot, and it would be great if someone
experienced with Buildroot could help me out.

First time through, I just ran "make menuconfig" and apart from
choosing i586 architecture, just accepted the defaults, and got a
target root filesystem.

Fine, but it only has runtime files and what I want is a basic cli
compiling environment for compiling some applications statically. So I
ran 'make clean' then 'make menuconfig' again, and made what seem like
the minimum changes to create a compiling environment in the target
rootfs.

It all goes well until compiling gcc for the target, and stops with this:

TARGET_CPU_DEFAULT="" \
	HEADERS="options.h config/i386/i386.h config/i386/unix.h
config/i386/att.h config/dbxelf.h config/elfos.h config/svr4.h
config/linux.h config/i386/linux.h defaults.h"

I also tried the latest snapshot of Builroot, same problem. Does
anyone know what is going wrong here?

The .config file is attached.
