Makefile.main cvs-tarball patch

When making Etherboot releases I often need to create a release  
tarball from CVS.  For a long time there has been code that did that  
in Makefile.main:

tarball: ../index.html ../index-berlios.html
         (echo -n $(VERSION) ''; date -u +'%Y-%m-%d') > ../VERSION
         (cd ../..; tar cf /tmp/etherboot-$(VERSION).tar --exclude  
CVS --exclude doc etherboot-$(VERSION))
         bzip2 -9 < /tmp/etherboot-$(VERSION).tar > /tmp/etherboot-$ 
(VERSION).tar.bz2
         gzip -9 < /tmp/etherboot-$(VERSION).tar > /tmp/etherboot-$ 
(VERSION).tar.gz

but it doesn't work if you're in a CVS directory because the names of  
directories aren't what is expected.

The attached patch does this:

cvs-tarball: ../index.html ../index-berlios.html
         (echo -n $(VERSION) ''; date -u +'%Y-%m-%d') > ../VERSION
         rm -rf /tmp/etherboot-$(MM_VERSION)cvs
         mkdir /tmp/etherboot-$(MM_VERSION)cvs
         cp -rP .. /tmp/etherboot-$(MM_VERSION)cvs
         ( cd /tmp; tar cf /tmp/etherboot-$(MM_VERSION)cvs.tar -- 
exclude CVS --exclude doc etherboot-$(MM_VERSION)cvs )
         bzip2 -9 < /tmp/etherboot-$(MM_VERSION)cvs.tar > /tmp/ 
etherboot-$(MM_VERSION)cvs.tar.bz2
         gzip -9 < /tmp/etherboot-$(MM_VERSION)cvs.tar > /tmp/ 
etherboot-$(MM_VERSION)cvs.tar.gz

Which lets one dump a tarball from a CVS directory to /tmp of the  
current Etherboot tree.

Not something that is generally useful, since most people don't do  
releases, but handy if you want make a quick tarball from CVS to run  
some patches against.

Suggestions and comments are welcome.
