The new test fails for me as well: Kubuntu 11.10, and config.log says:

That's the problem, and it's a big one.

That part doesn't matter until we can sort out why the linker can't find
dlopen. It's supposed to be in libdl.so, which Debian installs in
/usr/lib/x86_64-linux-gnu. Can you check that it's there (it might be in
/lib instead of /usr/lib)?
The error message in config.log is still unchanged. libdl.so is in
/usr/lib/x86_64-linux-gnu, as you guessed. Also the linker error message
doesn't complain about could not link 'dl' but it rather complains only
about the undefined reference. Hence, it found libdl.so but somehow doesn't
find that reference.
$ ls -l /usr/lib/x86_64-linux-gnu/libdl*

gnu/libdl.so - /lib/x86_64-linux-gnu/libdl.so.2
Also, please run grep lt_cv_dlopen config.log
lt_cv_dlopen=dlopen
lt_cv_dlopen_libs=-ldl
lt_cv_dlopen_self=yes
lt_cv_dlopen_self_static=no
So libtool.m4's call of AC_CHECK_LIB([ldl], [dlopen],...) found dlopen in
libdl.so.
More likely then that the command gcc -o conftest -I/home/cs/usr/include
-ldl conftest.c - lpthread
isn't trying to link libdl. Which is strange, especially since it works fine on
Debian Wheezy 64.
Hmm. That space between - and lpthread is bothersome. Try this patch and see
if it changes anything:
