Any dependency of dynamic libraries outside the sysroot are not found
at the moment, unless you use --rpath or --rpath-link.  -L doesn't
affect the DT_NEEDED search..

However, I guess ignoring -L for shared libraries is a little too
rude.  I'll have to try something different.  Looking first for
DT_NEEDED dependencies in the same dir as the library would fix the
particular problem I'm having.
