Hi Will,
I asked a similar questions some time before. Grant answered to my 
question "preserve toolchain", that he didn't manage to recycle the 
buildroot generated toolchain for a second run in an easy way. So it 
seems, that you are forced to from scratch including the toolchain if 
you do not use a "complete" external toolchain (e.g. generated with 
crosstool-ng).

Personally I didn't yet try out crosstool-ng because the current 
patchlevel of buildroot is a higher one (e.g. gcc 4.3.4 vs 4.3.5).

Regards,
Marcus
