3.5.3 essl

Use this flag only if you are linking with ESSL before linking with LAPACK. The problem is that ESSL uses a different calling sequence for DSYGV (and some other subroutines) than LAPACK. (At the moment the makefile for the RS 6000 links LAPACK before ESSL, so this flag is not required).
