+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
+```
