Thanks for doing this.  I think we should trim out the toolchain
versions a bit.  We shouldn't need anything older than 4.9.0, or maybe
even 4.9.4 now.

I also worry about making 7.x or 6.x be the default fetched versions
now.  I know gcc-6.x adds more warnings as I use the Debian toolchains
in my test builds.  So travis is going to go right to erroring out.
Since your patch is going to start with 7.3, can you please push this to
travis and see what fails, so we have an idea on how hard it will be to
move CI to 7.3?  Thanks!
