the modules are statically-linked into the ircservices executable.
This fixes the installation of chat/ircservices on platforms where
dlopen() doesn't obey its "mode" argument, e.g. RTLD_NOW. Unfortunately,
NetBSD/amd64 currently falls into this category (port-amd64/30570),
but this will also fix installation on any a.out NetBSD or OpenBSD
platform.
Approved for commit during the deep freeze by <agc>.
