Bug#895864: leptonlib: needs config.guess/sub update for riscv64

["Manuel A. Fernandez Montecelo" <mafm@debian.org>]

Version: 1.75.3-3
Severity: normal

Hi,

We are in the process of bootstrapping a Debian port for the riscv64
architecture (https://wiki.debian.org/RISC-V).

The files config.{guess,sub} included in this package are too old to detect this
system.

This package is quite important as it's a dependency of ffmpeg, and thus of all
of its many reverse-dependencies.

Debian Policy §4.3 recommends to update these automatically [1], one of the best
ways to achieve this is to depend on newer versions of debhelper (the current
level used by this package is deprecated) and use dh-autoreconf.

If you need help or want us to provide a patch, prefer that we NMU, etc., please
tell.

    "You should make sure that the configure utility detects the correct
    architecture specification string (refer to Architecture specification
    strings for details).

    If your package includes the scripts config.sub and config.guess, you should
    arrange for the versions provided by the package autotools-dev be used
    instead (see autotools-dev documentation for details how to achieve
    that). This ensures that these files can be updated distribution-wide at
    build time when introducing new architectures."


Thanks and cheers.
