[kaffe] rebuildLib for cross compiling

[Kiyo Inaba]

Looks like I forgot to submit this bug report...

After the introduction of rebuilding Kaffe library while making kaffe
(after 21/07/2002), we can not simply cross compile kaffe. It is
because libraries/javalib/rebuildLib (which is used to generate
library) tries to invoke newly compiled 'kaffe' which of course
should not work on the target machine.

Are there smart idea to avoid this problem?
