libdl -- Stub libdl.

DragonFly BSD (and FreeBSD) have the dlopen/dlfcn/... routines located in
libc. However many applications and their configure scripts look for these
routines in libdl. This adds a stub libdl with no subroutines, so that the
configure scripts pass. The dl* routines are automatically available via
libc.
