[Qt-creator] HowTo start Qt Linguist from External Tools with english language instead of current locale

[ekke]

I added an entry in QtCreator External Tools to start Qt Linguist from
there.
works well.

But QtLinguist start with german locale which is my current locale from OSX.

I prefer to use IDE's in english
In Qt Creator I can set the language, but I don't know HowTo change the
language to en in Linguist -
probably adding something to 'arguments' in external tools
didn't found a hint in the docs

thx helping
