Just so I'm on the same page, this is to autodetect
$libltdl_cv_sys_dlopen_deplibs correct? If so, why do you want to use
ltdl at all? Isn't it enough to write the following test programs
during the run of ltdl.m4:
('t1') dlopen test program 't2'
('t2') dlopen'ed by 't1' and depends on library 't3'
('t3') library depending on 't4'
('t4') dummy library
and then run t1. If you fail, libltdl_cv_sys_dlopen_deplibs=unknown.
If you succeed, libltdl_cv_sys_dlopen_deplibs=yes.
The purpose of 't2' is to detect if dlopen loads dependency libraries
and the purpose of 't3' is to detect if dlopen honours RPATH in a
library.
BTW, this probably isn't so trivial because you'd need to embed the
runtime path into programs 't2' and 't3'. You definitely don't want to
set LD_LIBRARY_PATH. Can you use the generated libtool program during
ltdl.m4?
