Configuring with --enable-static_link on Debian unstable
makes dmsetup fail to link:
/usr/lib/gcc/i486-linux-gnu/4.1.3/../../../../lib/libselinux.a(setrans_client.o): In function `fini_context_translations':
/build/buildd/libselinux-2.0.15/src/setrans_client.c:208: undefined reference to `pthread_mutex_lock'
...
/usr/lib/gcc/i486-linux-gnu/4.1.3/libgcc_eh.a(unwind-dw2-fde-glibc.o): In function `__deregister_frame_info_bases':

...
