The sudo/ldap support causes some build failures in static linking
configurations. See:
http://autobuild.buildroot.net/results/483/4830c69cc6a62080e1516f0d9009c2ba619c23c1/build-end.log
for an example.

From a quick look, it seems like sudo doesn't use pkg-config to
discover the ldap library, and therefore doesn't know that ldap needs
to be linked with openssl. But that's really a 5 seconds look at the
build error.

Could you have a closer look?

Thanks,

Thomas
