- use the compiler-driver instead of the linker

- adjust setting flags accordingly to use (hardcoded, see below) -Wl,
  Potential improvements:
  *) --warn-unresolved-symbols should perhaps be used for all libs
  *) eventually rename LDFLAGS to CC_LDFLAGS
  *) probe for compiler driver's notion of flag to use for passing in
     linker flags (i.e. don't hardcode "-Wl,")
