[V3 PATCH] Fix for defect report libstdc++/1886

[bumgard@roguewave.com]

This patch is required to allow file streams to be instantiated
on types other than char and wchar_t.

I am not sure this is the best way to solve this problem, but
it does follow the convention that the environment specific
implementation is kept outside of the common bits directory.

	* libstdc++-v3/include/bits/basic_file.h: Add #include for
	bits/c++io.cc to get implementation
