It depends on the linker, but with most of them, the order does
matter.

The Make variable for the linker is $(LD), not $(LN).

With one-pass linkers, such as GNU ld (and the other Unix linkers),
they are scanned left to right.  GNU ld can be optionally forced to
repeatedly rescan a group of libraries until all symbols are resolved
(see the -( and -) options).
