Bug#671834: libatlas3gf-base: Octave pinv function fails with message "illegal instruction"

[Andrea Brenci]

Package: libatlas3gf-base
Version: 3.8.4-3
Severity: important

To make the pinv function work I need to switch from atlas-base to
libblas and from atlas-base to lapack using update-alternatives.
My cpu is very old but from the package description I read:
"The libraries in this package are built without any processor extension
instructions, and should run on all processors of this general
architecture, albeit less than optimally."
So I expect the libraries to work even on old hardware.
This is my cat /proc/cpuinfo:
