Was there any controversy for architectures other than x86 / x86_64?  
While I'm not convinced it's sensible to try to support late-2016 
distributions running on kernel series dating from 2009, as I said in 
<https://sourceware.org/ml/libc-alpha/2016-02/msg00031.html>, changing the 
minimum for other architectures does allow a fair number of the cleanups, 
although not all of them.
