Update openoffice-4 with applicable changes in openoffice-devel r382334:

• Work around broken build on FreeBSD 11.0-CURRENT i386, which appears to be a code generation bug in clang 3.6 when using -Os optimization.
• Use the dictionaries already installed by ports.
• Update patch-*.mk patches to versions that were imported upstream. They are tuned for clang to use as is, with only some minor additional tweaks needed for gcc.
• Wordsmith pkg-message.
• Some Makefile cleanups.
