llvm dev - Nov 2019 - Bots which still pulling SVN will be removed from the staging

Hello everyone,

The following bots which are in staging and still working with SVN
will be removed at the end of the day tomorrow.

* llvm-riscv-linux
* llvm-avr-linux
* fuchsia-x86_64-linux
* fuchsia-x86_64-linux

along with the bots which are still missing dependencies to build from
github and without a sign that anybody actually care of them:

* clang-freebsd11-amd64

Please contact me if you are in the middle of porting and just need more time.

Thanks

Galina
