Miscellaneous jar improvements

	* patches/icedtea-jar-misc.patch: Import patch from upstream
	OpenJDK 6.
	http://hg.openjdk.java.net/jdk6/jdk6/jdk/rev/b35f1e5075a4


This is a patch to make jar much faster.  On Zero targets, this much
improves the build time, which is very painful on the distro builders.

OK for IcedTea trunk and 1.6 branch?

Andrew.
