Yes, this was just a little cleanup. I noticed that there was no
dependency on libdl.so from this library. I suspect this may have
original just been copied form another makefile.
In fact, the dlopen, dlsym, etc, functions (that are the usually the
cause for linking against ldl) are part of the standard C library
functions on Solaris, so ldl could be Linux specific. But I didn't want
to get too much involved in cleanup here.
