[coreboot] [PATCH] flashrom: Make packagers happy

[Carl-Daniel Hailfinger]

This patch introduces two new targets which are designed to make the
life of packagers easier.
In particular, it should no longer be necessary to patch the makefile
for hassle-free compilation.

The two new targets are:
make export
make tarball
Both preserve svn revisions and the exported tree does not depend on
subversion in any way or shape.

Documentation for this feature has been added to README.

+Packaging
+---------
+
+To package flashrom and remove dependencies on subversion, either use
+make export
+or
+make tarball
+
+make export will export all flashrom files from the subversion repository into
+a directory named flashrom-$VERSION-r$SVNREVISION and will additionally create
+a file .svnversion in that directory which stores the svn revision of the tree.
+
+make tarball will simply tar up the result of make export and gzip compress it.
