[CMake - TBB] TBB requires to link against libatomic on some non-x86_64 architectures

[VincentRouvreau]

Some non-x86_64 architectures seem to require explicitly linking against libatomic for the things that use TBB. I'm currently just adding it to the list of TBB libraries. Perhaps CMake can do something more intelligent on the architectures where it's needed?

@gspr Is this issue still relevant ?
I checked in other FindTBB.cmake files like the one in CGAL or this one and they never link against libatomic.
I also checked TBB release notes and TBB issue tracker and it is not clear to me when we need to link against libatomic

No, it seems that this is no longer an issue. I've removed the Debian patch for this for the 3.4.1 build, and things seem to be working fine. Thanks.

Thanks for the test, I am closing it.
