just c++.

Makefile: fix warnings when linking with clang++

Clang ignores some options during linkage and warns about it:

  clang: warning: argument unused during compilation: '-ansi'
  clang: warning: argument unused during compilation: '-Wp,-D_FORTIFY_SOURCE=2'

Add -Qunused-arguments to LDFLAGS to suppress the warnings.

Fix a compilation error when using clang++

Clang gives this error:

  In file included from opencv_trail_effect.cpp:25:
  ./Trail.hpp:13:22: error: in-class initialization of non-static data member is a C++11 extension [-Werror,-Wc++11-extensions]

  1 error generated.

Fix it to make compilation succeed.

Makefile: split compilation and linkage

This fixes an error when compiling with clang++:

  <builtin>: recipe for target 'opencv_trail_effect' failed
  make: *** [opencv_trail_effect] Error 1

The error happens because in this Makefile header files are in the
target dependencies, so they are added to the compilation command, but
clang does not support that when compiling and linking in the same

Also take care of using LIKN.cpp to link the program, as it is a C++
