Yes... not entirely clear that putting it in the vdso is a net win,
though. There are some people who would like to put a significant chunk
of libc in the vdso, and it just doesn't seem like a good idea.

An index table is somewhat more reasonable, but (a) not backwards
compatible (so wouldn't work with older kernels) and (b) has shades of
Windows...
