Ok, the absence of this patch makes me wonder who's actually building OpenJDK6 as it is upstream... :-)
Without: http://hg.openjdk.java.net/jdk7u/jdk7u/hotspot/rev/ca1f1753c866 the HotSpot in OpenJDK6 will fail to build on any version of Linux from 3.0 up. The original thread is here: http://mail.openjdk.java.net/pipermail/hotspot-dev/2011-July/004322.html and the patch applies cleanly to 6's HotSpot.
