  Log Message:
  -----------
  ofp-actions: Fix build on earlier GCC.

GCC4.4 gets confused by anonymous fields + flexible fields, complains:
lib/ofp-actions.h:510: error: flexible array member in otherwise empty
struct
lib/ofp-actions.h:512: error: bit-field ‘build_assert_failed’ width not
an integer constant
lib/ofp-actions.h:514: error: bit-field ‘build_assert_failed’ width not
an integer constant

Fix the problem by specifying the actions length as zero.
