 Hi Kenneth,

 What you're asking is unfortunately not simple...

externally. Any host tools that are needed by this script can be included in the
external toolchain.

Please explain this line?

It seems to me with an external toolchain, the biggest overhead after
a make clean is the host tools (especially if you build the linux
kernel separately too). If you need python or some other big package
building the host stuff is a major time sink. It would be wonderful if
the host tools could also be external to the build like the toolchain.
I did not know they could be part of the external toolchain?

Thanks, Steve
