Archives). A target has only one prerequisite on each other file it depends
on, no matter how many times each file is listed as a prerequisite. So if
you list a prerequisite more than once for a target, the value of $^
contains just one copy of the name. This list does not contain any of the
order-only prerequisites; for those see the `$|' variable, below.

I read the explanations before I posted the original. But they are not
clear to as there is no definition on what "order-only" mean? Does it
mean that $^ does not necessarily preserve the order but $| does?
Also, I suggest to revise the explanation to make it clear.

Ok. Question open, but just use:

This is like `$^', but prerequisites listed more than once are duplicated _in_the_order_they_were_listed_in_the_makefile. This is primarily useful for use in linking commands where it is meaningful to repeat library file names in a particular order.
