building openjdk without openmotif

[Yuri Nesterenko]

Hi Pieter,

lesstif is ok: the necessary headers are just the same,
and openJDK doesn't need anything else from a motif clone.
All you need is to define path to the headers in 
ALT_MOTIF_DIR, and then sanity should work properly. Where exactly in your
installation of lesstif you should point, you'll find after
a try or two. I personally keep just extracted headers somewhere,
without actually installing any motif.

Thanks,
-Yuri
