[icc + MKL 11.1 + NumPy] numpy.test() error: undefined symbol _intel_fast_memset

I am trying to compile NumPy 1.8.1 with icc 14.0.1 20131008 and MKL 11.1. 
The compilation succeeds, but when I run numpy.test() the test fails with this error message: 

ImportError: /tmp/tmpPXvMOC/test_array_from_pyobj_ext.so: undefined symbol: _intel_fast_memset

I am following Intel's instructions, I run intel's compilervars.sh to setup the environment and then build numpy with this command:

python setup.py config --compiler=intelem --fcompiler=intelem  build_clib --compiler=intelem --fcompiler=intelem build_ext  --compiler=intelem --fcompiler=intelem install --prefix=$HOME/.local 2>&1 | tee -a BUILD.log

With nm I found out that the _intel_fast_memset symbol is defined in libirc.so. I tried to add irc in site.cfg, but the error persists.
I also tried to compile numpy 1.9.0 and I still get the same error. I also tried to manually specify the libs in site.cfg instead of relying on mkl_rt, but the result is always the same.

The lib directories of the intel compiler are correctly set in the LD_LIBRARY_PATH, and the intel dynamic libraries are linked to _dotblas.so.
