RFA: Add libstdc++-v3 support for avr 7/7: Add missing qualifier for size_t in a couple of libstdc++-v3 tests

[Joern Rennecke]

A couple of tests fail because an unqualified size_t is used.

2014-09-15  Joern Rennecke  <joern.renne...@embecosm.com>

        * libstdc++-v3/testsuite/util/io/prog_bar.cc: Qualify size_t.
        * libstdc++-v3/testsuite/util/io/prog_bar.hpp: Likewise.
        * libstdc++-v3/testsuite/util/io/verified_cmd_line_input.hpp: Likewise,
