You have two choices:
1) Use the "-lfoo" syntax on the prerequisites list, and make sure that
the directory containing the libraries is listed via VPATH or vpath.
See the GNU make manual for how make handles these special
prerequisites.
2) Use functions to manipulate the contents of $^ when you run the
shell. Because it's a requirement that the libraries keep their
same order, this is very tricky to do. I expect you'll need to use
eval to do it. I suggest using option #1 :-)
