configure error for ssl on SunOS solaris 9

[Rolf Schrittenlocher <Schrittenlocher (at) rz.uni-frankfurt.de>]

Hi,

it took us some hours to find out the reason for the following error 
occuring during configure of 4.2 on Solaris 9:

"Checking for OpenSSL ...
Found OpenSSL include files in /usr/local/ssl/include
Undefined                       first referenced
symbol                             in file
dlsym                               
/usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)  (symbol belongs to implicit 
dependency /etc/lib/libdl.so.1)
dlopen                              
/usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)  (symbol belongs to implicit 
dependency /etc/lib/libdl.so.1)
dlclose                             
/usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)  (symbol belongs to implicit 
dependency /etc/lib/libdl.so.1)
dlerror                             
/usr/local/ssl/lib/libcrypto.a(dso_dlfcn.o)  (symbol belongs to implicit 
dependency /etc/lib/libdl.so.1)
ld: fatal: Symbol referencing errors. No output written to test-ssl
collect2: ld returned 1 exit status
gmake: *** [test-link] Error 1
WARNING: OpenSSL library files found in /usr/local/ssl/lib, but link fails.
Continuing with SSL support disabled."

The reason was that the link to ld was missing in Makefile.SunOS used by 
Makefile.test-ssl. Adding it as
NETLIBS = -lresolv -lsocket -lnsl    (org)
NETLIBS = -lresolv -lsocket -lnsl -ldl    (new)
in Makefile.SunOS solved the problem. I don't know if our solaris setup 
is somehow specific or ig this can be added generally to this file.

greetings
Rolf
