why so complicated? why not simply follow the installation
instructions in the User's Guide, set LIBDIRS accordingly to the
directory where you have MKL installed and let the configure script do
the rest for you.

besides, the flags you provide are wrong. you should consult the MKL
documentation for a (detailed and precise) explanation of how to link
with MKL. if you insist on setting things yourself.
