gnutls source code uses the C++11 <atomic> functionality since
7978a73346,
which internally is implemented using the __atomic_*() gcc built-ins
On certain architectures, the __atomic_*() built-ins are implemented in
the libatomic library that comes with the rest of the gcc runtime. Due
to this, code using <atomic> might need to link against libatomic,
otherwise one hits build issues such as:
../lib/.libs/libgnutls.so: undefined reference to `__atomic_fetch_sub_4'
on an architecture like SPARC.
To solve this, link against libatomic if BR2_PACKAGE_HAS_LIBATOMIC is set.
This fix gnutls build failures as well as cups, gnupg and libmicrohttpd
