Forgive me if it ever does not fulfill your requirements (you may want
to rely on GPR project files only), here is how I do when I need this
kind of linkage : I put some pragma Linker_Options ("-lkernel32");
pragma Linker_Options ("-lwsock32"); in the private part of
specification files.

Notice the "-l" as a prefix and the lack of any "-Wl,"

If you opt for this solution, make sure you put this in a
specification file which is required by all package which depends on
it (a root package is a good place).
