make installworld failing with locales due to broken symlinks

[NGie Cooper]

Hi,
	I run into this error when running `make installworld` with a world installed prior and during the projects/collation merge to head — reason is that the target for the symlink doesn’t exist. This might be fallout from recent build changes, or a side effect of the broken symlinks…
Thanks,
