--f90flags are used in compilation of fortran codes, not when
linking. For linking libraries use `-lname` and `-Lpath`
in f2py command line. But note that numpy/distutils/fcompiler/intel.py
should take care of linking intel compiler libraries. If it does not
work for your compiler, try to fix intel.py and send us your changes.
