Thanks for reporting that. I installed the following, and hope it
fixes things for you. At least, I bootstrapped successfully from
scratch after it. Dunno why I missed it before, perhaps because I
didn't do a full bootstrap.

* m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Renamed from
gl_USE_SYSTEM_EXTENSIONS, to fix a coreutils bootstrap failure
reported by Jim Meyering. All uses of cache variables renamed
to match Autoconf's.
(gl_USE_SYSTEM_EXTENSIONS): New macro, which simply requires
the other one.
