devel/icu preventing openldap24-sasl-client build

[Dewayne Geraghty]

openldap24-sasl-client has a new mandatory dependency on devel/icu.  Is
there any way to turn this dependency off, as I don't require this
additional 22MB source or its 18M package?

How it surfaced?
cd /usr/ports/net/openldap24-sasl-client
make -DBATCH  clean deinstall package
...
configure: WARNING: ICU not available

===>  Script "configure" failed unexpectedly.
Please report the problem to delphij at FreeBSD.org [maintainer] and attach the
"/var/ports/usr/ports/net/openldap24-sasl-client/work/openldap-2.4.39/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/sbin/pkg_info -Ea).
