webkit-efl: import from OE rev d4f0211e2078d5033ae0dee74664de5520d8392d

* currently it doesn't build with default pkg-config from oe-core
  http://lists.linuxtogo.org/pipermail/openembedded-core/2011-June/003798.html
  if build pkg-config-native before this patch
  http://cgit.freedesktop.org/pkg-config/commit/?id=69a7eaa6763bb0920e2b539fffbad51348d94deb


  then webkit-efl builds fine again
