Generally disabling libgcj for particular target architectures is obsolete 
at toplevel; toplevel knows what targets support libffi and disables 
libgcj for all other targets.

No existing target disables gcc at toplevel so I don't think you should do 
so.  But if you do so then it should be in a separate case statement 
alongside those disabling particular bits of GCC, not mixed in with those 
for other components.

This host-specific configuration doesn't make sense to me.  Remember that 
even if host and target are the same it could still be a cross compiler.  
Just disable sim and not gprof and be done with it.
