stat: fix printing selinux context and null-dereference

busybox stat tries to always print the selinux context, even if it
is not requested which leads to a segmentation fault due to
dereferencing a null-pointer.

This also changes the format-string used to print the context to
so it actually produces useful output.

 chvt, deallocvt, fgconsole
 findfs, hwclock, lspci, nmeter
 openvt, rdate, setkeycodes, smemcap

 or on devices like tablet pcs with special keys

 Tested on x86 and arm targets

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...

Android: final cleanup of new build system

Rename hidden config files to busybox-<profile>.config

Set also KBUILD_OUTPUT to prevent generation of files in src dir,
if local make without O= is made (which create host code)

That do not force the rebuild of config files, except with mm -B

Makefile: remove warnings on initial version check

Android.mk is using a SUBMAKE variable which is only
used to get busybox version as a CFLAG. This one has
the -s (--silent) makeflag. So ignore the KBUILD_OUTPUT
default value if this flag is present.

android: backport pty implementation from aosp/master

This is not (yet) in l-preview branch but on master
The only way to prevent duplicated includes was to
test the existence of a new constant added after
l-preview bionic source release.

Also use compatible hasmntopt() return type
(swapon/off compilation warnings)
