Secondary arch suggests the whole fedora collection is built with x32 ABI.
But there is one noticeable exception with that; as I understood:the
kernel will anyway "remains" at x86_64.
So that make me wonder if we really need to built the whole collection
as x32 ? Or if we only wants a selection of components to be optimized
by x32. For example does it matter to move the whole Xorg server
infrastructure as x32 or is it possible to leave it as x86_64 ? or is
there any benifit for the move to x32 in this area ?
