How do I find out if the julia binary is linked against MKL?

I have used the following options when compiling (in the Make.user file):

USE_INTEL_MKL = 1
USE_INTEL_MKL_FFT = 1

Just to make sure it is indeed linked against mkl, I tried this:

~$ ldd /home/kaiyin/opt/julia-0.6.0-rc1/julia
    linux-vdso.so.1 =>  (0x00007ffe85fec000)
    libjulia.so.0.6 => not found
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f748579e000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f7485596000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f7485379000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f7484faf000)
    /lib64/ld-linux-x86-64.so.2 (0x0000563aa3d8e000)

There doesn't seem to be anything related to mkl. Also, libjulia.so is "not found". Any suggestions?

BTW, I can start the julia repl without a problem:
