libdl does not always make cleaner Makefile for user programs and
user libraries, since all platforms do not provide libdl.so.
For instance, since FreeBSD-ELF has already included dl* in libc,
it will probably not provide libdl.so forever.
However, libdl will make cleaner Makefile for libc.

There is probably not much difference whether provide libdl or not.
However, I don't prefer to increase the number of libraries, since
it may make maching problem.  If libc depends on libdl, it seems not
necessary to separate into libdl.  And, I guess that if we provide libdl,
then we should change the soname and/or the major revision number of libc.
