In my gcc man page:

       -Wl,option
           Pass option as an option to the linker.  If option contains
commas, it is split into multiple options at the commas.  You
           can use this syntax to pass an argument to the option.  For
example, -Wl,-Map,output.map passes -Map output.map to the
           linker.  When using the GNU linker, you can also get the same
effect with -Wl,-Map=output.map.

And as -s is a linker option, it should probably we written as: -Wl,-s

But -s is basically what the 'strip' program does. So it doesn't hurt to to
leave them both out, and do a manual strip on the generated executable file
afterwards...

Bye, Wilfred.
