  Log Message:
  -----------
  [Driver] add -lresolv for all but Android.

As there 3 intercepts that depend on libresolv, link tests in ./configure scripts may be confuse by the presence of resolv symbols (i.e. dn_expand) even with -lresolv and get a runtime error.

Android provides the functionality in libc.
