[committed] libstdc++: Disable test for freestanding

[Jonathan Wakely]

Tested x86_64-linux with -ffreestanding.
Pushed to trunk.

-- >8 --

This test checks the exception-safety of std::stable_sort if copying a
value throws. For freestanding we don't allocate in std::stable_sort
anyway, and the exception thrown via __throw_runtime_error terminates,
so disable the test.

libstdc++-v3/ChangeLog:

	* testsuite/25_algorithms/stable_sort/mem_check.cc: Do nto run
	for freestanding.
