en_UK considered harmful

[Robert Brady]

I'm pleaded to note there is a British translation for gcc. Unfortunately,
this has been mislabelled - the correct country code in ISO 3166 for the
United Kingdom of Great Britain and Northern Ireland is for some reason
"GB", so the locale code should be en_GB, and not en_UK. [1]

en_GB is used by glibc, gnome, kde, etc, so please rename the file
appropriately. :)

[1] yes, the UK's tld is .uk, but that's only because we sneakily
    registered it anyway. .gb also exists (eg www.dra.hmg.gb).
