[Qemu-devel] [PATCH] configure: fix trace backend list for out-of-tree b

From: Greg Kurz
Subject: [Qemu-devel] [PATCH] configure: fix trace backend list for out-of-tree builds
Date: Wed, 26 Apr 2017 15:21:46 +0200
User-agent: StGit/0.17.1-20-gc0b1b-dirty

Since commit "c53eeaf75a04 configure: eliminate Python dependency for
--help", configure --help fails to produce the list of available trace
backends if invoked out-of-tree. It also spits the following error:

grep: scripts/tracetool/backend/*.py: No such file or directory

This patch simply adds the missing $source_path to fix it.
