It doesn't rebuild automatically right now.

I think that this is the main reason why I think 
the toolchain should be separate.

When the toolchain has been build it should generate
Config.in files automatically, which is included
by the Buildroot Config.in.

You will then have access to the toolchain
parameters, but you will not have the ability
to add packages depending on non avaialble options.

You will have to go back and reconfigure the toolchain
when then will then be forced to be rebuilt.

gcctools:	toolchain/.config
		make -C toolchain 
		touch $@

and then the toolchain is automatically rebuilt
everytime the toolchain configuration is changed.

If you can change an option easily which forces the rebuild
of a toolchian, then you can also change an option by
mistake making you lose a couple of hours...

If you separate the build then (almost) everyone will build
then native toolchain and then use it as an external toolchain.
