I guess what I'm saying is that on FreeBSD, the system built shared
libraries don't have libc recorded in them because we don't add -lc on
the commnad line to build them.

If i try to add -lc ldd doesn't show it as a dependency, but
readelf/dumpelf does show it as NEEDED. Is this the expected behavior?
Why isn't ldd showing the dependency?
