From 3be496834375256f15cb98812d92f9b3d6fcb3a7 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Fri, 29 Oct 2010 21:00:26 +0200 Subject: Optimize (-O2) host binaries by default Default HOST_CFLAGS to -O2, so host tools (like the cross compiler) are built with optimization by default. Based on a patch by Will Newton .
