[Lapack] Lapack-3.4.0 Installation error

Here make is trying construct an executable xblas1s.
The goal of xblas1s is to test the Level 1 BLAS single precision. 
The BLAS library you are providing is ESSL. The linker XLF cannot find the BLAS 
functions in ESSL.
This is the error messages you are seeing. 

You should either link with reference BLAS in Makefile.inc, or do not run this 
test, simply type "make lib". 

Julien.
