From 26082e79af64550d16fb1e314a904456b90a464e Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 20 Jun 2010 15:08:15 +0200 Subject: [PATCH] Introduce support for host config cache We now have for quite some time a configuration cache used to speed-up the execution of ./configure scripts when compiling programs for the target. This commit introduces a similar concept when Buildroot compiles programs for the host.
