You have to tell us exactly what you are passing, and send
configure.log.  Did you try the following?

--with-blas-lapack-lib="-Wl,--start-group  $(MKLROOT)/lib/intel64/libmkl_intel_lp64.a $(MKLROOT)/lib/intel64/libmkl_core.a $(MKLROOT)/lib/intel64/libmkl_sequential.a -Wl,--end-group -lpthread -lm"
