Actually, we don't really have this dimension. No libraries are built for
kernel-mode code; any code the kernel module requires from the rest of the
tree is built separately and linked directly into the kernel module. The
situation is similar for libuafs, though the other dimensions certainly
exist for that library as a whole.
Personally, I'd like to see a consistent set of libraries available in all
six forms (lwp/pthread x shared/pic/nonpic). However, note that for many
of our libraries, building pthread versions is more complex than just
changing a few compiler switches -- there is still a lot of code in AFS
which assumes that context switches can only happen at very specific points.
