F14-build size

[Yioryos Asprobounitis]

There is some discussion about the usability of F14 builds in relation to their size [1]
F14 builds are _really big_ for the 1GB XO-1 NAND leaving very little space for the user. If a few videos or wiki is installed or even try olpc-update you may run out of space.

I was wondering if unused locales could be removed (a la localepurge) at first boot or after language selection, modifying also accordingly `%_install_langs'. 
This should save considerable space and make F14 builds more usable for the 1 million XO-1s out there. 
Of course deployments could make heir own builds and modify them accordingly, but I'm sure that many places may not have this luxury.

I understand that we are in a feature freeze, but this could certainly be considered a bug, and a major one. 
Otherwise I think it certainly merits some consideration for 11.2.1
