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

edb at lapedb:/tmp/tmp/buildroot$ make external-deps gcc-.tar.bz2
gmp-5.0.1.tar.bz2
mpfr-3.0.0.tar.bz2
edb at lapedb:/tmp/tmp/buildroot$ make source
