You want a hard-coded path as rpath?

@iblis17 can you take a look at the julia build and see why it fails when MKLDNN is enabled?

[iblislin]

The log looks weird:
http://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/mxnet-validation%2Funix-cpu/detail/PR-13464/40/pipeline#step-500-log-223

+ export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so
+ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so
+ julia -e 'Pkg.build("MXNet")'

It doesn't match the code in this PR

    export LD_PRELOAD='/usr/lib/x86_64-linux-gnu/libjemalloc.so'
    export LD_LIBRARY_PATH=/work/mxnet/lib:$LD_LIBRARY_PATH
    # use the prebuilt binary from $MXNET_HOME/lib
    julia -e 'Pkg.build("MXNet")'

The line LD_LIBRARY_PATH is gone. Any idea?

[iblislin]

And I built a libmxnet.so at local.
I tried to load it with Julia, seems works.

julia> using MXNet

julia> ENV["MXNET_HOME"]
"/home/iblis/git/mxnet-mkl"

julia> foreach(Libdl.dllist()) do x
        if !contains(x,"mx")
         return
        end
        @show x
       end
x = "/home/iblis/git/mxnet-mkl/lib/libmxnet.so"
x = "/home/iblis/git/mxnet-mkl/lib/libmklml_intel.so"
x = "/home/iblis/git/mxnet-mkl/lib/libiomp5.so"
x = "/home/iblis/git/mxnet-mkl/lib/libmkldnn.so.0"

rpath change looks wrong
