[PATCH, 4.7] Enable the libstdc++ prettyprinters test suite

[Michael Hope]

The libstdc++ prettyprinters test suite isn't called out in Makefile.am.  Backport Andreas's
patch from mainline so that a sequential test run gives the same results as a parallel test.

Tested with no regressions on x86_64-linux-gnu and arm-linux-gnueabi.  The prettyprinter
tests are enabled as expected.

OK for 4.7?
