Locale data for en_US.UTF-8 and libc from cross-compile on amd64 system was tested on ref12-ppc64 to run tmux (it does work now).
It would be great if someone could test test this change on EB system, comparing the the /usr/share/locale contents for the builds without the patch/with the patch/cross-compile on EL system -- they should be exactly the same, obviously.
