Unfortunately it does not fix the build on i586-unknown-freebsd10.4. (Yes, I am trying various things to nail this one down and provide more input or make it reproducible for you, alas without success so far.) Some things I found is that - building for i686-unknown-freebsd10.4 instead of i586-unknown-freebsd10.4 does not make a difference. (I tried, since Jeff referred to successful i686 builds). - not just builds with the system compiler (clang 3.4.1) fail, but also those with GCC mainline from 20180827 do -- with the same failure mode.
