Fix issue with zero value handling in BLAS functions

+++ This bug was initially created as a clone of Bug #1117496 +++

Description of problem:

R is bundling a copy of BLAS specifically to resolve an issue where certain functions only operate on values when they are not equal to zero, but zero is a valid value in those cases. This patch resolves the issue (and has been sent to upstream LAPACK for resolution.)

Without this issue, R on EL-6 (and EL-7) does not operate correctly. We could work around this issue by using the bundled BLAS/LAPACK on those build targets, but we would strongly prefer not to do this.

There is a rather large userbase for R on RHEL (I know because I maintain R in EPEL and I get a lot of .edu and .gov emails when it breaks). Please take this patch and push the update asap.

Given the fact we are in production phase 3, I don't think this is item to be fixed in Red Hat Enterprise Linux 5. Closing WONTFIX for RHEL 5.
