Certain tools, e.g. compilers, are customarily prefixed with the name of their target platform so that multiple builds can be used at once without clobbering each other on the PATH. I was using identifiers named `prefix` for this purpose, but that conflicts with the standard use of `prefix` to mean the directory where something is installed. To avoid conflict and confusion, I renamed those to `targetPrefix`.
