intel-gpu-tools: backport patch fixing 32-bit builds

Fixes the following error seen in 32-bit builds:

| ../../intel-gpu-tools-1.20/lib/igt_x86.c:96:10: error: redefinition of 'igt_x86_features'
|  unsigned igt_x86_features(void)

I unfortunately missed this before merging the upgrade.

+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.
