Don't turn off mangling in implicitly extern "C" system headers. GCC
doesn't do this on any of the major platforms, and we don't really
support any of the platforms that do (nor will we actually handle
those headers well). Fixes PR6217; see PR6530 for details on what we
would need to do to support these platforms.
