user/mesa-amber: new package

This is the older branch of mesa intended for stuff like old and
big endian harwdare. It's feature-limited (no opencl, no llvm)
and fully replaces the regular mesa.

+From d72aa8ae74ffb7329003f9f23ffa05833af951ab Mon Sep 17 00:00:00 2001
+From: Jon Nettleton <[email protected]>
+Date: Fri, 14 Aug 2020 13:36:08 +0200
+Subject: [PATCH] radeonsi: On Aarch64 force persistent buffers to GTT
+
+This fixes a glamore corruption issue on the HoneyComb and by
+internet reports should also fix problems seen on Huaweii
+Kunpeng hardware.
+
+The root cause of the corruption needs to be worked out, but
+this patch also adds a noticable performance improvement. The
+aquarium webgl demo under chromium increases from 39-49 FPS
+when 5000 fish being rendered is selected.  Glmark scores also
+improve by ~200 with no specific tests showing any regression.
