[oe] classpath in 2011.03-maintenance

[Henning Heinold]

Hi,

we made some hacks bescause for some java packages javac fails at random and
we just try to recompile it for some rounds and have a higher chance to
get it done. To admit the ecj script is now diffrent from the one I wrote original,
maybee Stefan Schmidt made some more tweaks.

As side note we did not test classpath compiling for target architecture,
we only made sure classpath-native works, so we can compile openjdk
for the target.

Bye Henning
