The list comes from building all the cross targets listed in the 
MAINTAINERS file.  The problem of #ifdef code is one reason for posting 
this first - if things are cleaned up a little the removal task becomes 
much easier (a search of the GDB tree will be needed for each apparently 
unused function).

I don't know where solibs are at.

Actually, I suspect that they are needed - never got hooked up when 
merged from a branch :-(  My MIPS boxes are finally back up so I can 
check this.
