No sure why, but fix for #13633 has not made into the 8.8 branch. Due to 
this testwsdeque fails from time to time on POWER. Tested on 
ppc64le/ubuntu 18.04. Bootstrapped with ghc 8.6.3.

Is there any chance you may cherrypick Peter's fix in merge request 445? 
Would be great since otherwise besides some profiling related tests 
failing the build looks fine on ppc64le.

Thanks!
Karel
