gnutls: fix build on sparc
gnutls source code uses the C++11 <atomic> functionality since
https://github.com/gnutls/gnutls/commit/7978a733460f92b31033affd0e487c86d66c643d,
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, a configure.ac check is added to know if we need to
link against libatomic or not. The library is also added to gnutls.pc.
