OK -- so when someone undertakes to extend gas in such a way, these 
kinds of tests will be possible. This is, however not the goal of this 
implementation. Are you asking me to undertake this work as condition of 
acceptance?

How does this improve upon the existence of a real target (MeP) which 
generates these relocs, has a testsuite, and which could also be used as 
a template creating new target ports?
