okay, may be it tooks too long time to make me think it was building the
toolchain, maybe it was just building the kernel. Whatever.

When I said external toolchain, I actually's talking about Code Sourery
which can be selected from buildroot toolchain configuration menu. Maybe
she's now so external.

Anyway, for my real question, is there a solution? How to reuild the
root filesystem from scratch.  Thanks!
