Package idba FTBFS for mips and mipsel, powerpc and sparc with an error:

> g++ -Wall -O3 -fopenmp -pthread -g -O2 -Wformat -Werror=format-security -fopenmp -pthread -Wl,-z,relro -o idba_hybrid idba_hybrid.o  ../lib/libassembly.a

Mips platform does not have 64-bit __sync_* operations.
To avoid this behaviuor it is needed to use
corresponding __atomic_* from libatomic library.

Patch use-atomic-for-mips.patch contains these changes
of src/basic/atomic_integer.h for mips.

Patch add-libatomic-to-LIBS.patch
adds libatomic in LIBS, and as-needed in LDFLAGS into debian/rules.


I believe that this fix could be used for
sparc and powerpc, but unfortunately I
could not test it so I can not guarantee that.

Could you please consider including this patch?

Best regards,
