[Qemu-devel] [PATCH] Makefile: Put VERSION info into version.texi rather

From: Peter Maydell
Subject: [Qemu-devel] [PATCH] Makefile: Put VERSION info into version.texi rather than using -D
Date: Fri, 17 Feb 2017 15:12:20 +0000

Unfortunately some older versions of makeinfo don't correctly
handle the -D command line option and fail to set the variable.
This then causes them to complain
 docs/qemu-ga-ref.texi:41: warning: undefined flag: VERSION

Work around this by doing as the autotools do, and writing
the information into a version.texi file which we then
include from the .texi files that need it.
