+From 9dc3ca2c1c9fbb47e731551c6432df144f725261 Mon Sep 17 00:00:00 2001
+From: Yevhenii Kolesnikov <yevhenii.kolesnikov@globallogic.com>
+Date: Thu, 21 May 2020 18:58:47 +0300
+Subject: [PATCH] compilers: add fetching of define list for clang
+
+Simmilar to gcc, the list of pre-processor defines can be fetched with
+`-dM -E` option. The way cpu_family is determined on linux relies on
+this list.
+
+Fixes incorrect value of cpu_family on linux, when crosscompiling:
+
+```
+CC="clang -m32" meson ./build
+```
