Details:

This patch improves the detection of the Intel Math Kernel Library (MKL) in
AX_BLAS. New versions of the MKL cannot be linked with  "-lmkl -lguide
-lpthread", but instead require variations on "-lmkl_intel_lp64
-lmkl_sequential -lmkl_core -lpthread",depending on architecture, compiler &
other variables. See
http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/.

The present patch detects the architecture (x86_64 or i686) and compiler
(gfortran or others), but not the interface layer (assumes lp64 for x86_64),
threading (assumes sequential), static vs. dynamic (assumes dynamic), etc.

Tested on a number of different systems using gfortran and ifort.
