linux-libre-3.13-1: updating version
* reenable ALIX support * update patches and PKGBUILD * move preparation to prepare() * remove stuff from /usr/src, use /usr/lib/modules/$version/build instead * some PKGBUILD fixes * restore another option that got lost => CONFIG_MEM_SOFT_DIRTY * don't try to write to $startdir * fix broken symbols - this allows us to boot on i686 again! * add warning about missing keyboard support

+From 83460ec8dcac14142e7860a01fa59c267ac4657c Mon Sep 17 00:00:00 2001
+From: Andi Kleen <ak@linux.intel.com>
+Date: Tue, 12 Nov 2013 15:08:36 -0800
+Subject: [PATCH] syscalls.h: use gcc alias instead of assembler aliases for
+ syscalls
+
+Use standard gcc __attribute__((alias(foo))) to define the syscall aliases
+instead of custom assembler macros.
+
+This is far cleaner, and also fixes my LTO kernel build.
