Try to define environment variable

  LDSHARED=<path to the linker in /amd64 subdirectory>

and rerun the f2py.py script.

The support for intelvem compiler is defined in

  C:\Python27\Lib\site-packages\numpy\distutils\fcompiler\intel.py

See the end of this file, the last class definition might need an update..
