Good catch, thanks Graham.  I'll try to understand why BLAS is getting 
different treatment from libgmm here
I wouldn't have thought this particular point would be endian-sensitive, 
but perhaps it is.

If it's normal to get different BLAS behaviour here, then it'll be 
simplest to just drop the multiarch field.
