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

Disable gcc fetch when not internal toolchain

This is an old bug that's been lingering for some time now.
Try the attached patch, it should solve the issue.

Tested on 2010.11, works there for me.

Comment 3 Peter Korsgaard 2011-01-19 16:24:21 UTC

Committed a slightly revised version of the patch, which also disables the unneeded gmp/mpfr/mpc libraries, thanks.
