Full build log:
https://buildd.debian.org/status/fetch.php?pkg=cubicsdr&arch=mipsel&ver=0.2.0%2Bgit20170310%2Bdfsg-1&stamp=1491259779&raw=0
The problem occurs because mips 32-bit architectures does not support use of
8-byte atomics functions.
To solve this problem, it is necessary to provide linking with libatomic
library.
I have created and attached a patch that enables linking with latomic library
as needed.
With this patch package builds successfully on mips, mipsel, mips64el and i386.
Build for powerpc fails with same error and it should be solved as well.

Radovan
