Okay.  That seems like a good reason, and Ted is right anyway, we need to support clients who don't enable all targets.

I think we should probably continue (*) to require the x86-32/64 target in order to run the test suite:  it's good to have a standard target, it guarantees that we're testing codegen at two different pointer widths, most codegen tests are written against it, and the vast majority of developers will be running on it anyway.  So if we can agree on how to conditionalize tests based on targets, then I'll add the appropriate conditions to the (7 or so) tests that break on optional-targets builds, then reintroduce the target dependency from r97693.

John.

(*)  There are currently several codegen tests which test assembly output.  That's probably unfortunate, but it does mean that the test suite already depends on the existence of the x86 target.
