When building newlib, I am not seeing the configure script get
generated.  If I only patch configure.ac, the configure script stays
the same and my patch appears ignored.

Do you know what I could be missing?

I made this correction, and the --with-tooldir option only works
if I patch it directly into the configure script.

Could you help me figure out what is missing?
