mk/dlopen.buildlink3.mk is not covered in the pkgsrc guide.

When should it be used?

chat/gaim fails to build "silc" support for me under Linux.

===> Required installed package silc-toolkit>=0.9.12nb1: 
silc-toolkit-0.9.13 found
...
checking for silc_client_init in -lsilcclient... no
...
Protocols to build dynamically : gg irc jabber msn napster novell oscar 
yahoo zephyr

config.log has:

configure:29135: checking for silc_client_init in -lsilcclient

It configures fine on NetBSD 2.0.2 though:

===> Required installed package silc-toolkit>=0.9.12: silc-toolkit-0.9.13 found
...
checking for silc_client_init in -lsilcclient... yes

If I remove the patch-ad, it configures fine on Linux. patch-ad removes 
the -ldl.
