r261034: buildworld fails: undefined reference to `DES_ecb_encrypt'

With  r261034, I get the error shown below on one specific box running
kernel/world

11.0-CURRENT #0 r261034: Wed Jan 22 20:14:05 CET 2014 amd64

Another box compiles the same source without any problems (running
kernel/world 

11.0-CURRENT #4 r261091: Thu Jan 23 22:46:03 CET 2014 amd64

My buildworld process on all systems is to delete the content
of /usr/obj first before building the world/kernel, so remnants of
faulty code or inconsistencies regarding the source tree are not likely.

How to repair this strange behaviour?

Regards,

Oliver
