From 5782794e20f15f0f31207d9bc6f1350842532048 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 1 Mar 2010 20:34:47 +0000 Subject: [build] Disable ccache for embedded.o Embedded image support uses .incbin in inline assembly to include binary files. The file dependency is not spotted by ccache when deciding whether or not to rebuild embedded.o. This results in builds that contain an outdated version of the embedded image when ccache is used.
