r9063: - don't pollute the global $LIBS variable with -ldl

- -lresolve seems to not being needed any more
  (it's actually not used, and the build farm seem to happy with it)

- move socket and netif configure test to seperate files
- don't pollute the global $LIBS variable with -lsocket ...
- actually make use of the -lsocket when needed
  (should fix the solaris build)
