[healthcheck] Compile sources

Run the compiler on the globbed soruces.

The logger is used to capture the success and
failure compilation cases at the component level.
(If we were to compile the entire file directly,
we wouldn't get this granularity)

For now, we just log the number of success and
failures. In the future, we can provide a better
report building on this.
