It says that ha_mroonga.so which was linking with liblz4 isn't anymore.
I don't know why it happened, and maybe it's legit this time, but this
is exactly the situation for which this whole check was added, and
mroonga seems to have a lot of code related to lz4; so I will need
someone's (probably Sergei's) confirmation that it's expected before I
change the baseline. Or maybe Daniel knows why it has happened, that
will also be sufficient.
