Remove --source (-S) option

We are contemplating adding support for per-platform source directories in a
future release. Adding such functionality would make the -S flag harder to
understand, as some users may expect to be able to specify -S multiple times.

To avoid being stuck supporting -S after 1.2.0, remove it for now.
