Generally, removing features from your eCos configuration doesn't save 
you anything in your built image. eCos was specifically designed to make 
good use of link-time garbage collection; that is to say, if your 
application doesn't use a facility provided by the OS, the code for that 
facility does not appear in the final linked image. So to achieve a 
smaller footprint, you have to make your application use less of the OS.

An alternative strategy for you might be to start with the `minimal' 
eCos template and build up your configuation from there based on what 
your application actually needs. This may not save you very much, for 
the reasons described above.
