p11-kit needs binnmu on kfreebsd-* for new libc0.1

[peter green <plugwash@p10link.net>]

While looking at the buildd pages for liblas I noticed the following BD-Uninstallable explanation for kfreebsd-*

liblas build-depends on:
- libgdal-dev (>= 1.10.0~)
libgdal-dev depends on:
- libcurl4-gnutls-dev
libcurl4-gnutls-dev depends on:
- libgnutls-dev
libgnutls-dev depends on:
- libgnutls26 (= 2.12.23-12)
libgnutls26 depends on:
- libp11-kit0 (>= 0.11)
libp11-kit0 depends on missing:
- libc0.1 (< 2.18)

I would guess that this dependency was caused by use of private glibc symbols. The package was already binnmu'd on hurd for the new eglibc (linux does not seem to be affected).
