A linker table is a data structure that is stitched together from items
in multiple object files.

We already have a *bunch* of linker tables in Linux, mostly the init
tables, but they are all built in an ad hoc manner which requires linker
script modifications, which are of course per architecture.

My desire would be to make a general linker table facility so that a new
linker table can be implemented by changing C code only.
