Message:

Additions/Linux: under some circumstances chk_stubs.c can get built by C++.
bugref:9112: Linux Additions: fix building binaries for older Linux user space
chk_stubs.c is build during linker invocation to work around the build
system library order. Normally it is built as a C file, but apparently with
the right build flags it can be built as C++, so in that case make sure that
wrap_memcpy() is extern C.
