Created attachment 2863
  --> https://bugs.busybox.net/attachment.cgi?id=2863
.config illustrating this problem.

I tested this on 2010.11 and buildroot-20110117.tar.bz2, I tested this with a
real external toolchain/powerpc but for the sake of the exercise let's do this
as follows. Steps to reproduce:
   * Extract buildroot
   * make allnoconfig
   * In make menuconfig -> toolchain -> set toolchain type to external
toolchain, save the config
