root=dhcp dhclient segfaulting on F-11

[Warren Togami <wtogami-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

Harald applied fixes.  Now with root=dhcp it is failing to boot because 
dhclient is segfaulting.

ifup.eth0.561.out contains:
...
+ ip=
+ '[' -z '' ']'
+ do_dhcp
+ dhclient -1 -q -cf /etc/dhclient.conf -pf /tmp/dhclient.eth0.pid -lf 
/tmp/dhclient.eth0.lease eth0
/sbin/ifup: line 26:   563 Segmentation fault
...

dhclient.eth0.564.out contains only:
+ '[' -f /tmp/net..up ']'
+ netif=eth0
+ case $reason in
+ ip link set eth0 up
+ exit 0

dhclient.eth0.567.out contains:
+ '[' -f /tmp/net..up ']'
+ netif=eth0
+ case $reason in
+ setup_interface
... (and it sets it up properly via DHCP)...
... (but eth0 is not configured by the time it hits the shell)...

The following is a segfault at the emergency_shell when I have manually 
run "dhclient eth0".

Program terminated with signal 11, Segmentation fault.
