From 57b49737ae467fd95504de7b2d755a994e7cec4b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 7 Mar 2019 14:26:47 +0000 Subject: Makefile: Abstract out "identify the pkgversion" code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Abstract out the "identify the pkgversion" code from the rule for creating qemu-version.h, so it sets makefile variables for QEMU_PKGVERSION and QEMU_FULL_VERSION. (We will want to use these when building the Sphinx docs.) NB: As we abstract this out, we use -e to check for .git rather than -d, since in some situations .git may be a file rather than a directory.
