From 28cae90247bb2ce164eda37cd5cef41dd9e80108 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 27 May 2013 13:00:59 +0000 Subject: bzip2: improve the packaging Instead of doing some nasty SED tricks, use a patch that modifies the bzip2 build system to make it a little bit nicer. Those SEDs were made differently for the host and target packages, which is contrary to the logic of not having any difference in the source tree between the host build and the target build. This commit also makes sure that bzip2.mk behaves properly in a BR2_PREFER_STATIC_LIB=y context.
