Mike Frysinger has rejected this uclibc patch 
(http://article.gmane.org/gmane.comp.lib.gnulib.bugs/33613), but there is a 
different solution suggested for the coreutils build problem 
(http://article.gmane.org/gmane.comp.gnu.coreutils.general/4995). In the mean 
time I'm marking this patch as rejected in patchwork.
