Upgrade to Apache OpenOffice trunk SVN revsion r1833124. This includes
the bug fix in extra-patch-align16 needed for amd64. [1]

Instead of symlinking the directory containing the OpenOffice .desktop
files under $PREFIX/share/applications, symlink the individual .desktop
files. This is what upstream does on Linux and what LibreOffice does
as well. The Plasma 5 desktop ignores symlinks to directories when it
is scanning for .desktop files.
