Cool - yes, exactly!  We could make this work.

This is also a good idea.  jvgenmain could use these values to set up
non-empty .gcj_property and .gcj_property_info sections, so it doesn't
always have to be an extra step.

Getting this to work would help clean up some of our linker script
hacks for embedded targets (default thread stack size, for instance).

If we use jvgenmain for this, we'll have to make sure it can deal with
-D options in the absence of --main, because I know some folks have
hand written main()'s.
