package/armadillo: allow to select between lapack or openblas

Browse Source 
armadillo can use lapack or openblas as BLAS provider. LAPACK support is
optional.

This patch
- adds an _ARCH_SUPPORTS variable to check if one is available
- adds an option to choose lapack or openblas as BLAS provider

The choice is required since applications may potentially need lapack.
