Bug#728003: reuse this issue for the more general solution to use dh-autoreconf

[Matthias Klose]

Control: retitle -1 wxmaxima: run dh-autoreconf to update config.{sub,guess} and {libtool,aclocal}.m4

Reusing this report for the more general solution to also update
the libtool.m4 and/or aclocal.m4 files, needed for the port mentioned
in bug #726404.

See https://wiki.debian.org/qa.debian.org/FTBFS for a guide how to
address these.

Please ignore this email if the libtool.m4/aclocal.m4 update is not
needed, and updating the config.{guess,sub} files is sufficient.
