I used to try to do that with a complicated shell script that had one
option to use buildroot to build the toolchain, move it somewhere else
and fix it up. Another option would use buildroot to build the kernel
and a third would build the rootfs using that external toolchain.

After fighting with that for a month or two, I finally gave up.  Now I
use crosstool-ng to build the external toolchain; I build the kernel
separately; and I use buildroot to build only the rootfs.

It takes a little extra time to set up the three seperate build
scripts, but those three scripts are dead-simple and way easier to
maintain and use.
