Both x11-libs/libICE and x11-libs/libXdmcp are multilib-capable. However they currently have only "elibc_glibc? ( dev-libs/libbsd )" dependency, without "[${MULTILIB_USEDEP}]". If dev-libs/libbsd happens to be installed only for native ABI, while x11-libs/libICE and x11-libs/libXdmcp are built for 32-bit ABI and 64-bit ABI, then 32-bit versions of libICE.so and libXdmcp.so would not be linked against libbsd.so.0 library and would not contain undefined reference to arc4random_buf@LIBBSD_0.2 symbol. So there is no build failure, but automagic usage of arc4random_buf() in non-native ABIs.
