Not yet, because I'm not sure that GNU tar supports --xz yet.  You could
use '--use-compress-program=xz" though.

xz is be able to auto-detect the format of the compressed file (.lzma or
.xz) when decompressing.  However, to compress to .lzma, you need to
specify explicitly that you want the lzma format (xz format is the
default). There are two ways to do this:

xz --format=lzma ... other args ...

or use the lzma symlink

lzma ... other args ...

(Just in case you wanted to change the output tarball format...which you
can't yet, because setup.exe hasn't been taught about .xz. I plan to do
that soonish, with an ITP mingw-liblzma...)
