From 4fbb4b9c12d1944e5d60bc4f3d0cbd0bf7bed36d Mon Sep 17 00:00:00 2001

Subject: [PATCH] lib: Fix compilation on non-x86
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The meson build avoids the failure by excluding the igt_x86.c file from
the compilation. autotools being what they are don't support that in an
easy way, so just use the preprocessor to avoid the duplicate function
definitions.

Since igt_x86.c will now be ignored for non-x86 builds, the meson work-
around can be removed.

Upstream-Status: backport.
