It appears that this is not necessary.  I downloaded the OpenBLAS
substitute from hydra and built Julia locally on my notebook.  Julia
runs without problems.  It appears that OpenBLAS does detect the CPU
type automatically.

(There is a problem with our Julia package, which made me build Julia
myself.  Also seems to be related to CPU tuning.  Passing a make-flag to
force a generic build should fix this.)
