From ee0246e1e1d83f41985489c85dfef07098a2026d Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 29 Sep 2011 21:57:38 +0200 Subject: package: add configuration option to specify a local override file The user can now create a custom local override file to override the source directory for various packages. An example override file: ZLIB_OVERRIDE_SRCDIR = /tmp/zlib STRACE_OVERRIDE_SRCDIR = /opt/strace-4.5.20 would tell Buildroot to use the zlib and strace source code from the specified directories, instead of download, extracting and patching the code has done usually by Buildroot.
