As of commit 2d0f19d84ddb13412382674fd48e6fc5c2875d0e, Autoconf
*trunk* should now be backward compatible with the older std-gnu11.m4.
I verified that I can regenerate bison 3.7.4's configure script with
that version of Autoconf, making no other changes to the bison release
tarball, and then configure, build, and test bison with no errors.

The patch is somewhat invasive, though.  The full text is attached,
and before I merge it to the 2.70 branch, I'd appreciate any extra
testing and/or code review anyone cares to give it.
