[sr-dev] build failures on Debian SPARC

[Daniel Pocock]

The kamailio package appears to be failing on SPARC:

https://buildd.debian.org/status/logs.php?arch=sparc&pkg=kamailio

and this is preventing the package from propagating to the testing
distribution.

https://release.debian.org/migration/testing.pl?package=kamailio

This means it is not eligible for inclusion in the next stable release
of Debian.

This may not be hard to fix and it is also possible to just declare that
SPARC is unsupported and exclude it from building there.  As long as it
builds fine on all the other platforms then it should propagate to
testing/jessie
