Bug#1058818: Acknowledgement (grub-common: fwsetup --is-supported not supported, boots into setup instead)

[Georg Lukas]

This is probably related to
http://git.savannah.gnu.org/cgit/grub.git/commit/?id=26031d3b101648352e4e427f04bf69d320088e77
- if the config change from that commit is combined with an older grub2
binary, the binary will interpret `fwsetup --is-supported` as `fwsetup`
and immediately reboot into the BIOS setup.

This will happen when loading a new config from an old grub2, like the
one bundled with the Debian installer ISO/USB.

This also happens with the grub2 binary that's part of the 2.12~rc1-12
package - maybe it wasn't cleanly compiled? Or I have some older files
installed somewhere?!
