In order to support more complex specifications for cpus and architectures
we need to move away from using enumerations to represent the set of
permitted options.  This basic change just moves the option parsing
infrastructure over to that, but changes nothing more beyond generating
a hint when the specified option does not match a known target (previously
the help option was able to print out all the permitted values, but we
can no-longer do that.
