Subject: make: Make "src-tarball" target actually make a source tarball
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~4345
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=d5fb9fb71a880fe7dfb8c7de87397988520a4078;p=xen.git

make: Make "src-tarball" target actually make a source tarball

At the moment, making a release tarball is an annoyingly manual
process that involves running "git archive" into a temporary directory.

Script this process up and make a target, so that the release manager
can simply type "make src-tarball-release" and have everything show up
nice and neat in dist/xen-$version.tar.gz.  "make src-tarball" will
make a version number based on git describe, which will typically have
the most recent tag, number of commits since that tag, and the git
commit id of the current HEAD.
