Subject: [gnome-continuous-yocto/gnomeostree-3.28-rocko: 3326/8267] libbsd: Fix build with musl
Date: Sun, 17 Dec 2017 00:28:35 +0000 (UTC)
commit 9bf3f80e8862e9028a4f2115fbe2bc42a0b60a4f
Author: Khem Raj <raj khem gmail com>
Date:   Sun Nov 6 23:25:26 2016 -0800

    libbsd: Fix build with musl
    
    a.out.h support is not across all architectures only
    x86/x86_64 support is in linux/a.out.h, this patch
    abstracts the minimum needed constructs into itself
