Without linking to libpthread (bugs
https://bugs.gentoo.org/show_bug.cgi?id=473714 and
https://bugs.gentoo.org/show_bug.cgi?id=476866) we couldn't build some
of the tools that support SELinux (i.e. link with libselinux) whereas,
if we disable SELinux support, they do build properly (busybox is the
one most often found as it is used for our initramfs building so
generally one of the packages that is immediately seen - others might
exist like cryptsetup and such).

If another fix or approach solves this I'm too fine with this. It is
just something I know less about on how to proceed (not my cup of tea,
so to speak).
