Normally the ‘strip’ phase would strip things.  I guess the problem here
is that libraries are not in lib/, so nothing gets stripped.  This would
be worked around by simply passing something like:

  #:strip-directories '("OpenFOAM-1.2.3/lib")

Rather:

  (for-each delete-file (find-files "." "\\.o$"))

Paul can you confirm that this is OK?

If it is, could you update the patch accordingly, Dave?

Thanks,
Ludo’.
