I think disabling of target-boehm-gc for these targets was because they 
didn't support Java for various reasons.   However, ISTM that we'd need 
it for objc-gc.  So I think we shouldn't be adding these hunks at this 
point.

In theory we could build those targets after configuring with 
--eanble-objc-gc as a test.
