This sounds like it might be common bug, which we should workaround,
I guess at configure-time.

I can't reproduce the problem on my Debian GNU/Linux 3.0r1 box.
Does the following test program exit with nonzero status on your host?
If so, we could use it to see whether glibc is buggy.

#include <locale.h>
#include <string.h>
#include <errno.h>
int
main (void)
{
  setlocale (LC_ALL, "en_US.UTF-8");
  errno = 0;
  exit (strcoll ("abc", "def") >= 0 || errno
        || strcoll ("ABC", "DEF") >= 0 || errno
        || strcoll ("123", "456") >= 0 || errno);
}
