Multilib trickle appears to be broken and cannot interact with 32-bit
binaries. When attempting to do so the following is printed in the console:

ERROR: ld.so: object '/usr/lib/trickle/trickle-overload.so' from LD_PRELOAD
cannot be preloaded: ignored.

This renders trickle useless. It will continually attempt to work, but has
no effect on bandwidth.
