Turning off UseAuto/iterator.cpp test until recursive make issue fixed
    
The way 'make check-all' causes configuration files to be generated results in
the cpp11-migrate/Makefile not being triggered to generated any files. These
files are necessary for UseAuto/iterator.cpp to run. Turning off this test
until the problem is fixed properly.
