Am I right in assuming all these qt applications use one of the qt
classes?

I do wonder if this shouldn't be part of one of the qt classes as part
of a package_do_split_locales_append() or prepend() style function from
a code separation point of view. I do appreciate the need to influence
the list of locales although you could do that through directory
creation or an extra variable but we could enhance package.bbclass to
support that.

Regardless, this is changing ln under some weird circumstances.
Shouldn't the code adding this to the locales list be handling this
translation? I can see potential duplication between the arrays and a
host of other nasty bugs with this code as it stands :/. Please take
that regexp out of this loop at the very least.
