I thought the same thing, until my misconceptions were kindly corrected 
by others on the list.

I kind of forget the argument, but for cross compiler library (like 
libgcj) builds, the ${host} variable magically has the value of the 
cross target.  So everything works.

Libraries are hosted, tools that contribute the the generation of code 
are targeted.
