rpath & shared libraries in ghc 7.10.1

Suppose that I have :

//test.h
int add(int a, int b);

//test.c
int add(int a, int b){
  return (a + b);
}

//mylib.c
#include "test.h"

int testAdd(){
  return add(2,3);
}

Then I compile via :

gcc -shared -o libDir/libtest.so test.c
gcc -fPIC -c mylib.c -o mylib.o
gcc -shared -o libDir/libMy.so mylib.o -L./libDir -l test -Wl,-rpath=./libDir

Then I have Main.hs with :

module Main where
import Foreign.C.Types

foreign import ccall "testAdd" c_testAdd :: CInt -> CInt -> IO (CInt)

main = do
  result <- c_testAdd 3 4
  print result

and I have the associated cabal file :

name:                illustrate
version:             0.1.0.0
build-type:          Simple
cabal-version:       >=1.10

executable illustrate
  main-is:             Main.hs
  build-depends:       base >=4.8 && <4.9
  default-language:    Haskell2010
  extra-libraries:     test My
  extra-lib-dirs:      ./libDir

Then cabal repl works fine, but upon cabal run we get the following error :

cabal run
Preprocessing executable 'illustrate' for illustrate-0.1.0.0...
[1 of 1] Compiling Main             ( Main.hs, dist/build/illustrate/illustrate-tmp/Main.o )
Linking dist/build/illustrate/illustrate ...
Running illustrate...
/home/linux/Downloads/illustrate_withDir/dist/build/illustrate/illustrate: error while loading shared libraries: libtest.so: cannot open shared object file: No such file or directory

In #10442 (closed)##10492 (closed) trommler mentions that the problem arises because -rpath is not fed as an argument for libtest.so during linking.
