Subtle non-determinism building libc6

[Juro Bystricky]

A while ago I ran into some minor binary differences when repeatedly 
building libc6.

I filed a bug https://bugzilla.yoctoproject.org/show_bug.cgi?id=12291 , 
there is also a diffoscope

output that corroborates the claim.

Later on I also filed a bug with glibc:

https://sourceware.org/bugzilla/show_bug.cgi?id=22432

and based on the response I also sent in a patch with a proposed fix:

V1: https://sourceware.org/ml/libc-alpha/2017-11/msg00476.html

V2: https://sourceware.org/ml/libc-alpha/2017-11/msg00484.html


So far not much response, though
