linker set: Allow adding any variable into content
The newly created macro adds any kind of variable into a linker set. It
allows (for example) the saving an execution state of a function using
the following method:
- put a group of different variables into one linker set
- save the memory area containing the group of variables before the
execution of a function
- restore the memory area after the function has been executed
