For whomever is interested, I've finally got gettext + locales working on the 
I've done a lot of strace's on my development PC, to find out what files were 
opened by gettext / setlocale etc.
There usually is a locale database /usr/lib/locale/locale-archive, which you 
really don't want to copy to the Etrax environment.
On my system it is 19MB, and when I tried to create a new one, with just one 
locale in it (with localedef), it already was 1.1MB.

After this archive has been read, all subdirs in /usr/lib/locale are scanned, 
each of them can store a locale definition.
You can create a locale definition in a subdir, rather then in the archive, 
localedef -c -i nl_NL /usr/lib/locale/nl_NL (I'll use nl_NL as an example)

This creates some rather big LC_* files in /usr/lib/locale/nl_NL/
Each of them is required when you do
setlocale(LC_ALL, "") , even if only one of them is missing, the locale is not 

But I discovered that

setlocale(LC_MESSAGE, "nl_NL")

only requires /usr/lib/locale/nl_NL/LC_MESSAGE, which is a subdir with a 
system message file in it.
Luckily, this file is very small (only 54 bytes in my example).
And this is all that's needed to make gettext switch to the nl_NL messages.

Now in the devboard_82, glibc is installed in /lib, so also the locale stuff 
has to be in /lib/locale rather then /usr/lib/locale.

So I created several locales in /lib/locale, and now I can select different 
languages with setlocale(LC_MESSAGE, "xx_XX")
