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.)
