dlsym() in libc vs libdl

On my S10 U-something system, dlsym() is defined in both libc and
libdl. Is there a difference between the two? The man page doesn't
say anything about linking with libdl, and on my system it works
correctly without it.

But my software has a reported bug whose symptom indicates that dlsym()
isn't working. I haven't yet been able to verify that that is indeed
what's going on, but Magic 8-Ball says "Signs point to yes".

'dis' can't find dlsym() for some reason so I can't easily take apart
the two libraries for comparison.
