mkkickstart generates an invalid line "lang en_GB" which causes anaconda
to fail.  The only valid en_ entry in the file 
/usr/src/redhat/BUILD/anaconda-7.1/lang-table
is "en_US". 


Reproducible: Always
Steps to Reproduce:
1. Install 7.1 with GB/UK localisations
2. Run "mkkickstart | more"
3.
	

Actual Results:  
***WARNING: you will need to set the static IP address in the configuration
file
lang en_GB
 
#network --bootproto static --ip 10.0.0.1 --netmask 255.255.255.0 --gateway
10.0.0.254
 
cdrom
 
device ethernet eepro100
 
keyboard "uk"
 
zerombr yes
clearpart --linux
part swap --size 518
install
----etc...----

Expected Results:  Maybe:
lang en_US


Although this can be corrected by hand, the kickstart process still
prompts for the language setting !
