The problem is how we calculate the number of descriptors, which needs the
size of the descriptor array for each architecture.
Define another global variable to export the size of descriptor array?

Pass it as an argument?

The num_desc can only be initialized in the same file that defines the
descriptor array.
Looks like we have to have a global variable to save that. The
solution would be similar
to have a statically defined header for each arch.
So, keep the header structure for each arch?
