Subject: Link libatomic against wsclean-lib on riscv64 and fix FTBFS
Dear maintainer,
wsclean failed to build on riscv64:
```
[100%] Built target wsclean-shared
/usr/bin/ld: libwsclean.a(msgridderbase.cpp.o): in function `MSGridderBase::getAvailableMemory(double, double)':
./obj-riscv64-linux-gnu/./gridding/msgridderbase.cpp:300: undefined reference to `__atomic_exchange_1'
collect2: error: ld returned 1 exit status
make[3]: *** [CMakeFiles/wsclean.dir/build.make:154: wsclean] Error 1

dh_auto_build: error: cd obj-riscv64-linux-gnu && make -j4 "INSTALL=install --strip-program=true" VERBOSE=1 returned exit code 2
make: *** [debian/rules:10: binary-arch] Error 25

```
Attached is a patch that links libatomic on riscv64 and fixes FTBFS, tested on
my QEMU riscv64 machine. Please let me know if I missed something.
Cheers,
Eric
