please remove yaboot-howto from CVS

[Colin Walters]

Hi,

The upstream maintainer of yaboot doesn't want the yaboot-howto
(english/ports/powerpc/inst/yaboot-howto.sgml) to be maintained in the
Debian CVS; he'd rather do it himself.  I've tarred up the current
version and translations and set them to him; could someone please
remove them from our CVS?
