I have rebuilt an earlier version of virtualbox, that sets Rules-
Requires-Root: no and added extra ls statements to find where/when/why
setuid bits are getting lost after fixperms.

make[1]: Leaving directory '/<<PKGBUILDDIR>>'
   debian/rules override_dh_strip
make[1]: Entering directory '/<<PKGBUILDDIR>>'
ls -latr debian/virtualbox/usr/lib/virtualbox/VBoxSDL

It seems to me that either dh_strip or something it calls (strip,
debugedit) looses the setuid permission in hirsute and up.
