From 18ff4f166beef62175a81e9ffc7390d4a0ae5b64 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 10 Jul 2014 21:06:04 +0200 Subject: build system: create .xcompile dependency It's probably safe to say that .xcompile needs an update if util/xcompile/xcompile changed, so tell make about this dependency. Updates are honored immediately due to GNU make's feature of reinterpreting everything when an included file changes. See "How Makefiles Are Remade" in the GNU make documentation for details.
