Fix Bug 0073: [Re] Add dummy routine in timer to avoid compiler problem

Bug reported by John Tellefson to LAPACK Mailing List on February 7th.
Dummy routine was removed in LAPACK 3.3.0 because it seems it was working on all machines.
[Re] Incorporation of the dummy routine and incorporate John's suggested cosmectic changes to allow
an easier change in number of operation to perform.

"modified secondtst.f from lapack-3.2.2 with the old
code that makes it reliably report timing loop results. I also added a
variable TOTAL to simplify changes in setting array size and iterations
which affect total flops and made few other changes.
