Ah, okay I see what you mean now. And I'm afraid that the answer is
"sort of", because linking static libraries (albeit of pic objects) into
shared libraries is non-portable, do libtool can't really support it
reliably.
If the target architecture of your target machine supports `pass_all'
in dep_libs_check_method (like linux does) then it will work. But it
is still non-portable, which may be a consideration for you.
The portable (but complicated) way to it, is to have your make rules
extract the pic objects from the static archive with $AR, and link all
of those objects into your plugin. There is already code in libtool
that does something similar with convenience libraries (which are
after all static `ar' libraries of pic objects) if the host compiler
doesn't do --whole-archive, so you can probably start from there.

You're welcome.
Cheers,
