  Yes, DejaGnu has been able to do this since it was created. The rough
concept is called a Canadian Cross. We used to use telnet, to use ssh
you'd need an ssh server, but Cygwin works quite well.

  I'd suggest using the ABE tool
(https://git.linaro.org/toolchain/abe.git/), not sure what ARM uses now,
but Linaro uses ABE. ABE does support build a windows hosted toolchain.

  You don't need to do this.

  It's a mix of board files, and the global site.exp file.

  DejaGnu handles all of this.
