It's from glibc's tree.  That's where I got it.  Sorry I gave the wrong impression.

Somehow I thought I had this working with fewer iterations than that.
I'm somewhat distracted at the moment -- I wanted to make things
easy on myself and test my cross-build script by building an x86
cross compiler, and am learning that's not so easy on an x86 box!
My latest kludge is a patch that does lots of this:
-    ac_cv_prog_cc_cross=no
+    ac_cv_prog_cc_cross=yes
:-)
