I don't think it's appropriate to require unreleased versions of external
packages. A proposal to use autoconf 2.70 should wait until it's been
released. (And until it's widely present in GNU/Linux distributions I
think pretty strong justification would be needed to use it, even after
it's been released.)
I'm also doubtful that making the /var/run path configurable is an
appropriate change at all. This path appears in _PATH_VARRUN in
sysdeps/unix/sysv/linux/paths.h, an installed header. In general it's
best for installed headers to depend only on the (architecture, OS) pair
(with architecture being interpreted so that e.g. 32-bit and 64-bit get
the same headers), not on other configuration variants. If there is
consensus on /run being the right path on GNU/Linux, then the change
should simply be made unconditionally (with appropriate documentation in
NEWS).
