Do you have suggestions on how the ifdef should look?  It is pretty ugly
now.

To make progress, I pushed by this by switching target CPUs and ran into
a
more general problem.  The $(LINK) command for the libffi test does not 
appear to go looking for newlib in the build tree.  

To continue on, I put a - in front of that line and then got to boehm-gc
and told it to use POSIX threads for RTEMS.  That got me to the point
where
it wanted to know about memory layout.

Which all leads me to a more general suspicion... has anyone every used
the GNU Java libraries on an embedded target?  

Looking at the configure's and target configuration files, I am not 
finding many signs that another embedded target has ever been worked
on.  
If I am in uncharted territory, then I will need some help if anyone
cares about this getting pushed into the embedded space.

THanks.
