libdrm: Set _XOPEN_SOURCE and _GNU_SOURCE
Several POSIX extensions are used in the libdrm code (e.g., mknod and ffs). Set _XOPEN_SOURCE and _GNU_SOURCE to something reasonable to ensure that prototypes for these functions are available. This is done in configure.ac using AC_USE_SYSTEM_MACROS. This requires autoconf 2.60 or later. Eventually the code should check for the existance of these defines and do something reasonable if they are not available. Inspired by a patch by Pauli Nieminen and suggestions from Julien Cristau. Thanks. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
