FYI - ltmain.in patch

[Gary V. Vaughan]

You may have noticed that the mdemo-static.test series has been
failing for the last week or so.  Having fixed libltdl to correctly
extract the dependency_libs setting from the pseudo-library, the
following bug was revealed:

When lt_dlopen()ing a preloaded library with libtool libraries as
deplibs, ltdl then tries to tryall_dlopen each of these dependencies.
With mdemo (for instance) libfoo2.la depends on libsub.la, so
lt_dlopen()ing libfoo2.la tries to also dlopen libsub.la, which fails
for a static only build (since libsub.la is not preloaded, and ltdl
cannot load the shared component of libsub.la since it was built
static only).

The problem is especially wierd because libsub.la *is* statically
linked into mdemo -- however, libltdl cannot see those symbols in the
preloaded_symbols table so they cannot satisfy the deplib requirements
of libsub2.la.  They do however satisfy the undefined symbols in
foo1.la, since foo1.la doesn't list libsub.la as a deplib.

I have applied the attached patch, which fixes the bug by dlpreloading
all libtool library deplibs of all preloaded libraries -- in the case
of mdemo libsub.la is actually linked in twice: once to satisfy
foo1.la; and then again as a preloaded library to satisfy libfoo2.la!

Cheers,
        Gary.
