ARC: enable more options to satisfy build requirements of applications

ARC: enable more options to satisfy build requirements of applications

As reported by Buildroot autobuilder following options were missing:

 * Libutil stub (UCLIBC_HAS_LIBUTIL option)
   http://autobuild.buildroot.org/results/ce3/ce39eb9b9ece0968563641fb2207099d1a37b191/

 * Program_invocation_name (UCLIBC_HAS_PROGRAM_INVOCATION_NAME=y)
   http://autobuild.buildroot.org/results/154/1546d909e606daefd41b87dece94d642c0fdeba4/
   http://autobuild.buildroot.org/results/bd5/bd54581d7b0cc73bc501072d27e870a443dfce79/

 * Ifaddrd support (UCLIBC_SUPPORT_AI_ADDRCONFIG=y)
   http://autobuild.buildroot.org/results/134/134e78ef1fa87f7fbf26c23ec5dfc68785d79613/

 * Libnsl (UCLIBC_HAS_LIBNSL_STUB=y)
   http://autobuild.buildroot.net/results/331/331ed781b422448205fb9e7c9730ec0c438d6306/
   http://autobuild.buildroot.net/results/402/402d64965ac7ac6e1d4e1990080394958802fe8c/
   http://autobuild.buildroot.net/results/960/9605bac2972d3e3d3fb91947ae6921e89210247b/
   http://autobuild.buildroot.net/results/6b6/6b61ea80a3a6dcead233c4b408eba8b8d647e841/

* UTMP got reworked recently, which breaks packages such as busybox, gdbserver
  etc so enable that too

Enabling mentioned options to make sure more packages could be built with ARC pre-built uClibc tools.

Note UCLIBC_USE_NETLINK is a prerequisite for UCLIBC_SUPPORT_AI_ADDRCONFIG.
