integrating the arm bytecode interpreter into IcedTea

[Matthias Klose]

What does it take to integrate the arm bytecode interpreter written by Edward
into IcedTea? I currently build it as a set of extra patches applied to the
Ubuntu packaging, which works ok. Ed provided another fix to make it work on
armv4 as well, so we don't need any explicit configuration option anymore (?).
Afaik Xerxes did want to test a build on armv4; I don't have access to armv4
only hardware.
