Change-Id: I994fb45c6f7c7d07bb843429b42f25bb8192e4da
android: add a switch to handle Android L

restore support of wait3()
librpc: inet_makeaddr() is now in bionic

nslookup modified (_res is now hidden in libc dns)
tested on kitkat and built on l-preview

Note:
 With static version built on l-preview,
 nslookup doesnt work on kitkat due to a new socket flag
 named SOCK_CLOEXEC (0x80000), bacon kernel could be
 incompatible with this socket option (to check) or
 dnsproxyd could be not compatible.

 To be tested on a real Android 5.0 build later...
