Considering that the whole point of prelinking is to optimize the link
location and avoid collisions among a large set of dynamic link
scenarios, it only makes sense when run on an entire link-tree branch
from the trunk to the leaves. There is no way that I know of to tell
prelink to avoid prelinking (modifying) glibc, for example, while
allowing it to prelink all the rest of the system, since the if it
linked glibc first in a large link area that had been prelink-associated
to everything else, the linker would have to fall back to normal linking
for everything prelinked to it. non-ld Run-time linking wouldn't cause
that problem, but init-time linking using ld would.
