+	Fix for compiling glibc with -march=i686 specified.
+	The patch below found at: http://permalink.gmane.org/gmane.linux.lfs.devel/9758,
+	a nice discussion (with a comment of the glibc maintainer) can be found here:
+	http://old.nabble.com/-RFC-PATCH--glibc-doesn%27t-build-with-%22gcc--march%3Di686%22-td17442608.html
+	
+	To me, this simply shows once more how fucked up things can be. E.g. the (related) bug report here:
+	http://bugs.gentoo.org/show_bug.cgi?id=201815. There are lots of duplicates to it, many people are
+	affected, one can find really elaborate reports. And the responsible gentoo developers are too
+	elite to even point to the actual patch fixing the issue.
