       not simple since different platforms often call them different

       Or perhaps we should just try and guess based on the names of
       the libs that need to be linked to (though that doesn't cover
       deps on other programs rather than C libs).

How about asking the distribution specific package manager program to which package the library file belongs? However, this requires that the dependent package is installed on the packaging machine.
