Hi,

either GCC 4.6.1 or Ubuntu add -Werror=format-security to the -Wall set, 
so libxl compilation breaks:
   libxl_create.c: In function 'store_libxl_entry':
   libxl_create.c:454:9: error: format not a string literal and no 
format arguments [-Werror=format-security]
   cc1: all warnings being treated as errors

attached patch fixes this and another occurrence.

Patch from: Uwe Dannowski

Signed-off-by: Andre Przywara <andre.przywara@amd.com>

Regards,
Andre.
