From 0559332abd04b6c8bc70171d201f43d2e4735336 Mon Sep 17 00:00:00 2001
From: Lee Chee Yang <chee.yang.lee@intel.com>
Date: Wed, 2 Sep 2020 08:28:35 +0800
Subject: [PATCH] Improve Reproducibility for src package
Improve reproducibility for intel-graphics-compiler-src package.
needs to pass build path as environment variable to the build.
this only works on bison 3.7 onward, hence check for bison version
before adding the flags.
Upstream-Status: Inappropriate [applying --file-prefix-map in such way does not work for upstream]
