Deprecated targets are exactly those in the "# Obsolete configurations." 
list in config.gcc (targets requiring --enable-obsolete to build them).  
The only architecture for which all configurations are currently 
deprecated is mep.

Of course, such deprecated targets should still have all their 
documentation present, bug reports kept open, etc. - it's only when 
support for a target is actually removed from GCC that documentation etc. 
is removed and bug reports closed (as WONTFIX).
