[PATCH] linker_lists.h: drop never used ll_start, ll_end macros

[Rasmus Villemoes]

These macros have AFAICT never been used at all. It's also far from
clear what purpose it could serve - for one thing, what _type would
one pass, other than void perhaps? The example using "struct
my_sub_cmd" seems misplaced, as how could one know that the first
linker list consists of those, and moreover, how would one know how
many there are?

The linker list concept is fragile enough on its own, there is no need
to have unused functionality lying around that may or may not bitrot
and certainly will confuse readers of linker_lists.h.
