util/testing: Add a few build tests using all cores

We've had issues in the past where building with a sufficient number of
processors would expose a previously hidden timing issue in the build.
Those have frequently been in the path of a single chip or architecture,
so this adds a few different builds.

I'd like to have a representative sampling without increasing the build
time too much so maybe in the future, we can modify the clang build
targets to be different than the GCC targets.

These can be updated to different targets over time.
