Currently we look for dlopen() in -ldl. We *don't* look to see if we
get dlopen without that library. So on a system without that library,
like Tru64 5.1, the plugin support (including all KDC-side database
access) will be broken.

The failure mode for not having a plugin system implemented is to
quietly not find any plugins, and let the caller deal (or fail to).
For example, from kdb5_util create:

create: Unable to find requested database type while creating database '/home/raeburn/krb5/krb5-1.5/alpha/Install/var/krb5kdc/principal'

Over Zephyr, Russ pointed me to AC_SEARCH_LIB, to use instead of
AC_CHECK_LIB. Look into it....

Cy Schubert confirms this is a problem for building on FreeBSD as well.

... and Dennis Davis, likewise, for OpenBSD.

When fixing this, we might also make this stop the configure or build process, on platforms
where we build KDC binaries that we know would be broken.
