How can I make a simple CROSSTOOL for choosing a newer GCC?

Bazel is using my system's version of gcc (which points to gcc-5).
Instead, I want to use gcc-7.

I don't see any way to configure or pass in a different compiler,
which means I must specify it as a CROSSTOOL.

I've read all the CROSSTOOL tutorials, but I'm still confused on how to configure this newer version of gcc, because there are so many potential options.

Is there a way to get the default CROSSTOOL configuration used?
Because then maybe I could just tweak that to a different compiler.

Otherwise, could anyone point me to a typical standard configuration of using gcc-7.
I am able to change my system version of gcc to point to gcc-7, and that builds correctly, which is why I'm looking for the simplest CROSSTOOL configuration that essentially does the same thing.

If you're talking about the autoconfigured crosstool that is shipped with bazel, you can just set CC environment variable to point to the gcc-7.
