lwIP is not currently buildable for BSPs that have not been explicitly 
added to the build. The first step would be a mostly-unified lwipopts 
that provides defaults that are overridable by BSP-specific or possibly 
user-provided configuration. The only reason I see to allow this is if 
we want to let users bring their own lwIP drivers without incorporating 
them into the rtems-lwip integration repository.

I'll look into better management of BSP-specific configuration and 
making a generic build available for BSPs that don't have a particular 
configuration available.
