Setting solib-absolute-prefix is a the way to subtract searching from
the root since it either searches <abspath> or
<solib-abs-pref>/<abspath>, not both. Don't know if it's practical for
you but we explicitly set solib-absolute-prefix in our init functions so
we never have to worry about accidentally getting /usr/lib/somelib.so
instead of $SDK_ROOT/usr/lib/somelib.so.
