x264: add from meta-oe, update and tweak
This is required by the default configuration of libav being brought over from meta-oe. Changes from the meta-oe recipe: * Update to the latest revision from the stable branch (upstream does not seem to provide stable releases.) * Add LICENSE_FLAGS = "commercial" * Enable PIC to fix text relocation warnings and disable warning for i586 (since PIC can't be used there) * Make SUMMARY value slightly shorter * Indent SRC_URI consistently with other recipes in OE-Core Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>
