try either of the following:
1) modify your make.sys according to the following lines:
LDFLAGS        = -static-intel -Wl,--start-group /opt/intel/mkl/lib/intel64//libmkl_intel_lp64.a /opt/intel/mkl/lib/intel64//libmkl_sequential.a /opt/intel/mkl/lib/intel64//libmkl_core.a -Wl,--end-group -lpthread -lm
BLAS_LIBS      =   -lmkl_intel_lp64  -lmkl_sequential -lmkl_core
LAPACK_LIBS    =

2) run the configure script using:
./configure LDFLAGS="-Wl,--start-group ${MKL_PATH}/libmkl_intel_lp64.a ${MKL_PATH}/libmkl_sequential.a ${MKL_PATH}/libmkl_core.a -Wl,--end-group -lpthread -lm"
where MKL_PATH=/opt/intel/mkl/lib/intel64

Anyhow, you can also refer to the following link:
http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/
where, by selecting the INTEL compiler/mkl version you use and your platform, the correct way of linking to mkl
is shown.
