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:
