Bug#689623: libx11: autoconf update for arm64 building

[Wookey]

Package: libx11
Version: 1.5.0
Severity: wishlist
Tags: upstream patch

This package needs autoconf updates (to config.guess and config.sub)
to build for 64-bit arm. The arm64 port is stalled until this package
is updated.

Support for aarch64 has been added to autotools config.guess and
config.sub in autotools 20120210.1

For upstream running autoreconf against autotools-dev 20120210.1 or
later will fix the autoconf part.

For the Debian package, if you wanted to keep this up to date
automatically in the future (generally a good idea) then adding
something like this to your distclean target would be effective: -test
-r /usr/share/misc/config.sub && cp -f /usr/share/misc/config.sub
config.sub -test -r /usr/share/misc/config.guess && cp -f
/usr/share/misc/config.guess config.guess (You could instead just make
those files links.) along with a build-dependency on autotools-dev

Please pass this bug report to upstream (I hope I have CC:ed the right
person in this report)
