[Pkg-dns-devel] Bug#830942: pdns: FTBFS on m68k and powerpcspe: missing __atomic_{load, fetch_add}_8

[Aaron M. Ucko]

Source: pdns
Version: 4.0.0-1
Severity: important
Justification: fails to build from source (but built successfully in the past)

The m68k and powerpcspe builds of pdns failed:

Please try explicitly linking against -latomic, perhaps with
-Wl,--as-needed to avoid incurring a dependency on it on other
architectures.

Thanks!
