Add necessary infrastructure to support "nano" build of newlib.

ARC aproach to this feature is similiar to ARM's one here.

2016-04-29  Anton Kolesov  <anton.kolesov@synopsys.com>

        * arc/nano.specs: New file.
        * arc/Makefile.in: Support nano.specs.
        * arc/nsim.specs: Likewise.
