[Pkg-postgresql-public] Bug#790543: Update config.{sub, guess} for arm64

[Martin Michlmayr]

Package: slony1-2
Version: 2.2.3-1
User: debian-arm at lists.debian.org
Usertags: arm64

slony1-2 fails to build on arm64.  According to #751722, autotools-dev
is used to update config.{sub,guess}, but I get:

> Invalid configuration `aarch64-linux-gnu': machine `aarch64' not recognized
> configure: error: /bin/bash config/config.sub aarch64-linux-gnu failed
