Subject: libstdc++: Add _Exit to <stdlib.h> for freestanding

libstdc++: Add _Exit to <stdlib.h> for freestanding

When I added std::_Exit to the freestanding declarations in <cstdlib> I
should also have added it to <stdlib.h>.

libstdc++-v3/ChangeLog:

	* include/c_compatibility/stdlib.h [!_GLIBCXX_HOSTED]: Add
	using-declaration for _Exit.
