fakeauth segfaults on debuild

[Simon Law]

        I downloaded hurd-cvs.  I go into the directory, and edit
debian/changelog to my satisfaction.  I then run `debuild -r
/bin/fakeroot` which causes /bin/fakeauth to segfault.  Apparently, I
cannot run `/bin/fakeroot debian/rules clean` but I can run
`/bin/fakeroot /bin/make debian/rules clean`   This is all done as a
normal user, of course.

        What do you guys think?
