Building libjava takes forever on any platform, relative to the rest of 
the compiler build.  That's why I often disable it, especially since I 
don't use Java very much, and gcj even less often than Java in general. 
  Do you really *need* gcj on these embedded platforms?

Also, I don't really think that bootstrapping GCC directly on target 
hardware is very useful -- except for testing GCC.  I'd build GCC on 
some fast workstation, even if I eventually wanted it to run native on 
the target.
