Linking to memcached failing with : "undefined reference to `evthread_use_pthreads'"

[dho...@us.ibm.com]

I am trying to build the latest couchbase source (master) on Ubuntu16.04 with ppc64le platform. 

At the build level its failing with below error : 

[ 75%] Linking CXX executable ../memcached

../libmemcached_daemon.a(libevent_locking.cc.o): In function `setup_libevent_locking()':

/root/meghali/couchbase/kv_engine/daemon/libevent_locking.cc:27: undefined reference to `evthread_use_pthreads'

collect2: error: ld returned 1 exit status

kv_engine/daemon/CMakeFiles/memcached.dir/build.make:119: recipe for target 'kv_engine/memcached' failed

make[2]: *** [kv_engine/memcached] Error 1

CMakeFiles/Makefile2:11718: recipe for target 'kv_engine/daemon/CMakeFiles/memcached.dir/all' failed

make[1]: *** [kv_engine/daemon/CMakeFiles/memcached.dir/all] Error 2

Makefile:138: recipe for target 'all' failed

make: *** [all] Error 2

I found a similar bug being raised at the couchbase issues page, however the fix it mentions is already merged at master still its failing.

The issue link for reference is : https://issues.couchbase.com/browse/MB-23836?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aworklog-tabpanel

Can someone please help me understand the issue and provide some pointers around it? 

Thanks,
