It is a long-standing issue.  The deal is that libsupport (and many 
others) are .a files.  If one of the .o files in the .a file is used by a 
plugin, but not by the tool, they will get link errors.  There isn't a 
good solution to this, I'd rather keep libhello as a santity test rather 
than a test for a complete solution.  :)

For any specific client, they can do things to link the needed .o files 
in.  For example, we could make opt reference a symbol in 
slowoperationinformer.  I don't think it's important enough to do this 
though.
