Source: primesieve
Version: 6.2+ds-1
Severity: serious
Tags: upstream
Justification: fails to build from source (but built successfully in the past)

Builds of primesieve for armel, mips, mipsel, and the non-release
architectures m68k, powerpc, powerpcspe, and sh4 have started failing:

  libprimesieve.so.8.2.0: undefined reference to `__atomic_fetch_add_8'
  collect2: error: ld returned 1 exit status

On these architectures, you should be able to find this symbol in
libatomic.  I'd suggest linking with -Wl,--as-needed -latomic
everywhere so that you don't have to special-case any platforms or get
formal dependencies on libatomic on the platforms that don't need it
here.

Could you please take a look?

Thanks!
