Yes, it made a difference to me. I was building a set of
tools that would be used by product developers and release
engineering to build firmware.

I found that when I used a pre-built native gcc, etc to
build the crosstools, that I ended up with library
dependencies in the crosstools on the native tools
I used to build the crosstools, and that was unacceptable
in my case, so I used those native tools to build my
own set of native tools first, and made them part of the
build environment, so we had full (reproducible) control
over everything we build and deliver, and building the
product didn't depend on the builder having access to
the same exact external native toolset I used.

I don't know if that makes a difference to you or not.
If you don't build your own set of native tools, the
crosstools will depend on the libraries from the blastwave
stuff when you run them. You can see that if you run
ldd on the resulting binaries.
