This serves two purposes. It helps to prevent regressions
and it allows focus on features that still don't export properly.

The standard .mk file had trouble on the Mac, so I ended up copying
ooxmlimport.mk instead of trying to tweak the export template.

The huge section of tests excluded from Win32 testing is still
excluded here.

The ole-anchor test works as export in the import code, but didn't
work from the ooxmlexport directory, so left that one as import only.
