 MacPorts can build ports "nice" so that they allow other CPU-intensive
 processes to take precedence. When this feature was added to MacPorts, it
 broke some ports, such as ocaml, because of the way they were setting
 build.cmd; see #16091. The solution to that ticket was to disable the nice
 build in this case, but I think we can do better and enable nice builds
 even in this case.
