Title:
  rrr:no dh_strip or strip loose setuid bit

Status in binutils package in Ubuntu:
  New
Status in debhelper package in Ubuntu:
  Fix Released

Bug description:
  Over at https://launchpadlibrarian.net/550715513/buildlog_ubuntu-
  hirsute-amd64.virtualbox_6.1.22-dfsg-2~ubuntu1.21.04.2_BUILDING.txt.gz

  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
  -rwsr-sr-x 1 buildd buildd 406808 Jul 29 14:34 debian/virtualbox/usr/lib/virtualbox/VBoxSDL
  ...
  dh_strip --dbgsym-migration='virtualbox-dbg'
  debugedit: debian/virtualbox/usr/lib/virtualbox/VBoxSDL.so: Unknown DWARF DW_FORM_0x1f20
  a7cf3c43c8b18c3261d2d4737a475bf730ad1554

  ls -latr debian/virtualbox/usr/lib/virtualbox/VBoxSDL
  -rwxr-xr-x 1 buildd buildd 166208 Jul 29 14:35 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.
