* rebuilding with a different value of such a setting will rebuild
* in a different output directory; this will result in higher disk
* usage and more work the first time you rebuild with a different
* setting, but will result in less work if you regularly switch
* back and forth between different settings.
*
*
With one important exception, it's sound to choose any subset of the
* config's components for this string, it just alters the dimensionality
* of the cache. In other words, it's a trade-off on the "injectiveness"
* scale: at one extreme (output directory name contains all data in the config, and is
* thus injective) you get extremely precise caching (no competition for the
* same output-file locations) but you have to rebuild for even the
* slightest change in configuration. At the other extreme (the output
* (directory name is a constant) you have very high competition for
* output-file locations, but if a slight change in configuration doesn't
* affect a particular build step, you're guaranteed not to have to
* rebuild it. The important exception has to do with multiple configurations: every
* configuration in the build must have a different output directory name so that
* their artifacts do not conflict.
*
*
The host configuration is special-cased: in order to guarantee that its output directory
* is always separate from that of the target configuration, we simply pin it to "host". We do
* this so that the build works even if the two configurations are too close (which is common)
* and so that the path of artifacts in the host configuration is a bit more readable.
