[Debian-iot-maintainers] Bug#829623: libcoap: FTBFS on non-Linux: unsupported operating system

[Aaron M. Ucko]

Source: libcoap
Version: 4.1.2~rc+git20160626-1
Severity: important
Justification: fails to build from source

Builds of libcoap for kFreeBSD and the Hurd have been failing with
errors along the lines of

  checking operating system... configure: WARNING: ==> Currently unsupported operating system x86_64-pc-kfreebsd-gnu!
  configure: error: ==> If you can provide patches to support your operating system please write to 'libcoap-developers at lists.sourceforge.net'.

Please either implement support for these architectures (bearing in
mind that they still use GNU libc) or adjust the package's overall
Architecture setting to linux-any.

Thanks!
