I've had a google around for some more information, and it comes down to it 
being part of glibc (and by extension eglibc).  There is a whole page of 
information at 
http://www.gnu.org/s/libc/manual/html_node/glibc-iconv-Implementation.html. 
It is part of the character set conversion functions that are part of glibc. 
I understand from Yann's comments that uclibc doesn't include this folder 
(therefore either handles this another way, or doesn't at all!).

Further information is at 
http://www.gnu.org/s/libc/manual/html_node/Generic-Charset-Conversion.html.

Maybe if buildroot can determine that the external toolchain is glibc/eglibc 
based, it can simply then copy this folder over.  Below I've included a 
listing of the files contained in the folder (at least in my case). 
Basically they're all .so files, but there's also a 'gconv-modules' text 
file that holds the configuration data.

Maybe, for those who won't want / don't need it there could still be a 
buildroot configuration option controlling the copy, but the default 
position to do the copy?  Or maybe this should be something at the crosstool 
end?

Cheers
Andy
