Update libre/qemu-user-static and dependencies
Fighting with glib2 was no fun. But hey, at least I got a GCC bug report
out of it! https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85957
To get around this, I enabled SSE2 for glib2-static. This means it won't
run on pre-Pentium 4 (2001) i686 processors; which will cause problems on
the Pentium Pro/2 and the Pentium 3, and their AMD competitors: K6 and K7
(the latter of which was branded as Athlon, Athlon XP, Duron, and Sempron).
https://lists.parabola.nu/pipermail/dev/2018-May/006748.html
If someone digs out a Pentium 2 and gets Parabola to boot on it, I'll
figure out a different way to get around glib2's disagreement with x87
floating point math; and turn SSE2 back off.
