As the matter of fact, on the same build system defconfig + STATIC_LINK +
UML_NET_VDE is enough to reproduce it.

Toolchain:
	libc6		2.11.2-10
	vde2		2.2.3-3
	gcc		4.4.5-8
	binutils	2.20.1-16

all from stock stable/amd64.  Note that debian has the original of that
patch in their user-mode-linux package; see http://bugs.debian.org/494995
for history.
