added build script to build the tricore-gcc toolchain

Initial step to get support for Tricore GCC to the live site

Hello,
thanks for your contribution!

Hmmm, would have been nice to have it along all the other gcc build we have... Have you tried to build it using ct-ng? If not, maybe I can try that. That would make our maintenance easier

Since the tricore-gcc is now supported by ct-ng, how to proceed now?

You can create the several PR to add support for tricore:

• gcc-cross-builder: add a config file for the target that works inside the docker image
• add the tricore targer in the infra repository
• update main site config for all enabled languages (there's an helper script for that in gcc-cross-builder)

I can take care of it, but it will take some time. If you want it ASAP, you should probably try to provide us with some (or all) of the above.
