> FYI  This runstatedir stuff is a feature not in the last FSF autoconf
release from 2012, but present in some linux distros.  To avoid this
problem, you shouldn't use /usr/bin/autoconf or automake.  Rather, you
should build them directly from FSF autoconf/automake sources, using the
same version that is mentioned in the comments at the top of the generated
files, and then use your own programs when regenerating toolchain files.
If you did that, then you wouldn't have a change for this file.  The same
change would also be missing from other Makefile.in files.  But this is a
minor issue, and will likely be fixed next time someone regenerates the
files.

The autoconf-2.69 we use was released in 2012.  There are now autoconf 2.70
(Dec 2020) and 2.71 (Jan 2021) releases.  If we upgraded to a newer
autoconf release that would fix this problem.  Though of course it might
cause other problems.  A lot of stuff could have changed in the last 9
years.

The patches look OK to me also.
