I assume that it is okay to have undefined symbols in convenience

libraries that will be used as modules -- the pic objects are
built normally, and are not expected to resolve all their symbols
until they are linked into a library; convenience libraries are
then rolled using 'ar' and 'ranlib' (or equivalent) which also do
not check whether symbols are resolved.  We now build each of the
loaders as a convenience library module under these assumptions,
and link libltdl.la with selected modules, at which time all of
the symbols *are* resolved:

* TODO: Remove item addressed by this changeset.
* libltdl/Makefile.am (lib_LTLIBRARIES): Remove libdlloader.la.
(libdlloader_la_SOURCES): Declaration removed.  Changed all
clients.  Source files..
(libltdl_la_SOURCES): ...added back in here.
(libdlloader_LDFLAGS, libdlloader_la_LIBADD): Removed.
(libltdl_la_LIBADD): Remove libdlloader.la; add $(LTLIBOBJS).
* libltdl/loaders/Makefile.am: Removed all references to
libdlloader.la.

1.2. libtldl
------------
* Get rid of the shared libddloader.
* Change libltdl interface: add separate functions for function
pointers. This will allow porting to systems where function pointers
are incompatible with data pointer C-wise.
